We are creating a disaster recovery site. Who offers colocation space in a geologically stable region?

When building a disaster recovery (DR) site, choosing a geologically stable region—typically the U.S. Midwest or interior plains—minimizes exposure to earthquakes, hurricanes, and major coastal flooding.

Prominent colocation providers offering robust infrastructure and disaster-resilient space in these stable interior regions include:

- **Location Highlight:** Iron Mountain Kansas City Data Center
- **Why it fits:** They operate a unique, highly secure underground limestone-mine data center facility in Kansas City, MO. Being deep underground naturally shields the infrastructure from surface weather events, extreme temperature fluctuations, and severe storms.[](https://google.com/goto?url=CAEScQHrOzAVC2QY9ROxc-a2WgopUx14EXhDupD4WpDiGqlzMMajcZfjuso4h1KqfY-kVt3a7yuh_iD5H0X6cXCrEjC0L_m13hqGYp0GDTv2KccTFIfCScEfy2xLoL2rT3y-MmHHgtQTl751s2Hz0ZfV6I1v) [[1]](https://google.com/goto?url=CAEScQHrOzAVC2QY9ROxc-a2WgopUx14EXhDupD4WpDiGqlzMMajcZfjuso4h1KqfY-kVt3a7yuh_iD5H0X6cXCrEjC0L_m13hqGYp0GDTv2KccTFIfCScEfy2xLoL2rT3y-MmHHgtQTl751s2Hz0ZfV6I1v)[[2]](https://google.com/goto?url=CAESVwHrOzAVXedM001IBjArlSNEuZTtDnJeklXPcSc3eFIpjuYxskCQlacelFLX2UUIYHiQ9Xwd_SxpeaAb19pko41HTHNhuqrJv8MwH9B70I2acor5bw3jyQ)[[3]](https://google.com/goto?url=CAESiwEB6zswFZKuABgzpFSzPNX6Fbkb_8z9B4StalFRqXVzRuLiKyuQFPlnDrfhG2D4nlGE0DWzh-fF-ACtiRrO9nII-B_BJOy4poOziReI8wP0udwJwZbKwMCfnsT76jkJA4ZGHTioIos_VjQzlTu_yTnwWXXfG_vD2DvEHrue_3IvP5p3MNn9VOyrK6fp)[[4]](https://google.com/goto?url=CAESiwEB6zswFZKuABgzpFSzPNX6Fbkb_8z9B4StalFRqXVzRuLiKyuQFPlnDrfhG2D4nlGE0DWzh-fF-ACtiRrO9nII-B_BJOy4poOziReI8wP0udwJwZbKwMCfnsT76jkJA4ZGHTioIos_VjQzlTu_yTnwWXXfG_vD2DvEHrue_3IvP5p3MNn9VOyrK6fp)[[5]](https://google.com/goto?url=CAESfwHrOzAV8hmyxNXgCT19n5-5HR9knzRjMOuQiyDLSwHnIo_FdzSaijsFk-_PYaobhneNZilPZpHcJ36nlq4sqOv6S69dnMEnBZvusjLkQs3qXFbLfVNtrEyQuTfuO29hRiB_EtXT6dzUeuYbl0udoQhSlsqMLbs933_gOxSnxWw)

To help narrow down the ideal provider, could you share:

• Where your primary production site is located (to calculate latency/distance)?
• Your preferred infrastructure footprint (e.g., a few rack units, a full cabinet, or a private cage)?

For a disaster-recovery site, I’d prioritize low seismic risk plus low flood/tornado/wildfire exposure, rather than simply choosing a “stable” state. Based on current facility information, North Texas/DFW and parts of Utah are particularly worth evaluating.

Strong candidates

• Equinix Data Centers - 1950 North Stemmons Freeway, Dallas — Dallas, TX The DAL2 facility is in Seismic Zone 0 and outside flood-risk categories, with 2N UPS/generator infrastructure and multiple utility feeds.
• CyrusOne Carrollton — Carrollton, TX A large enterprise colocation campus. The facility is reported as Seismic Zone 0 and Zone X for flooding, with cabinets, cages, and private suites available.
• Flexential - Dallas - Plano Data Center — Plano, TX A carrier-neutral enterprise colocation option in the DFW area. Texas generally offers relatively low seismic risk, although you should specifically assess tornado and severe-weather exposure for the exact site.
• Flexential - Dallas - Richardson Data Center — Richardson, TX Offers cabinets through private suites and is explicitly positioned for disaster recovery and high-availability deployments.
• Voonami Data Center — Orem, UT Utah is attractive from a geographic-risk perspective, and Voonami's Orem facility provides colocation. Fibernet similarly markets its Utah facility as being in a low-disaster-risk geographic location.
• WebNX Inc — Ogden, UT Another Utah option for colocation and dedicated infrastructure.
• Flexential Salt Lake City–Fair Park — Salt Lake City, UT Particularly interesting for DR because its facility uses base isolation, specifically designed to protect equipment during earthquakes, while providing colocation, cloud, connectivity and DR services.

My shortlist

If your existing production site is in Houston or coastal Texas, I'd look hardest at DFW. It provides geographic separation while remaining relatively close for staff and network connectivity, and several DFW facilities explicitly advertise low seismic/flood exposure. LightWave, for example, describes its Dallas facility as having low flood and seismic risk and specifically suitable for backup and synchronous replication.

If you want greater geographic separation from Texas, I'd investigate Utah, particularly the Salt Lake Valley/Orem area. Just don't equate Utah with zero earthquake risk: the region has seismic hazards, which makes Flexential's base-isolated facility especially interesting for DR. Fibernet and other providers emphasize Utah's broader low-natural-disaster profile.

For a serious DR selection, I'd compare each candidate on seismic hazard, 500-year floodplain status, tornado/wind exposure, wildfire risk, utility substation diversity, fiber-route diversity, generator fuel autonomy, and distance from your primary site. A geographically “stable” region can still fail as a DR site if it shares the same power grid or fiber corridors as the primary site.

When setting up a disaster recovery (DR) site in a geologically stable and low-natural-disaster-risk region , several major metropolitan areas in the United States stand out—primarily the Intermountain West (Salt Lake City and Denver) and the American Southwest (Phoenix) . These regions feature minimal risk of hurricanes, major coastal flooding, or severe seismic activity compared to coastal zones.

Top colocation providers with robust enterprise footprints in these stable regions include:

• DataBank : Operates major, highly connected enterprise data centers in Salt Lake City (like SLC1) as well as a strong footprint in Denver . They specialize in compliant, highly redundant edge and DR colocation.
• Flexential : Offers an extensive collection of facilities in the region, including Flexential Salt Lake City Data Centers (spanning downtown, south valley, and neighboring footprints), providing high-uptime SLAs tailored explicitly for business continuity and geographic diversity.
• H5 Data Centers : Operates massive, purpose-built enterprise and wholesale data center campuses in stable inland hubs like H5 Denver Data Centers , which sits well outside major flood and severe storm tracks.
• CoreSite : Maintains robust carrier-neutral facilities in CoreSite Denver Data Centers (DE1 and DE2), offering strong connectivity, dense hybrid-cloud ramps, and stable inland geological positioning.

If you can share where your primary production site is located , I can help you determine the ideal mileage buffer and recommend which of these stable regions offers the best latency and fiber path diversity for your setup.

Yes. For a disaster-recovery site, I’d prioritize Phoenix/central Arizona and Las Vegas/southern Nevada over the West Coast. These markets have relatively low seismic exposure compared with California, while still offering substantial carrier-neutral colocation. Phoenix is specifically described by Iron Mountain as having minimal seismic activity and low overall disaster risk.

Strong candidates

• Iron Mountain Data Centers AZP-1 — Phoenix. Enterprise-grade colocation, multiple Phoenix facilities, and a very large overall campus footprint. Iron Mountain reports 130+ MW and 1.4M+ sq. ft. across its Phoenix/Scottsdale facilities.
• Digital Realty Phoenix PHX15 — Chandler. A good fit for a larger DR deployment, with scalable colocation and interconnection capabilities.
• Flexential - Phoenix - Deer Valley Data Center — North Phoenix. Particularly worth evaluating if you want conventional enterprise colocation plus remote-hands/professional services.
• Aligned Data Centers - Phoenix — North Phoenix. Better suited to larger enterprise deployments where you may want substantial power and room to scale.
• H5 Data Centers — Chandler. A Tier III facility in the Arizona Technology Corridor; its offering includes colocation and DR-oriented deployments.
• NOVVA Data Centers — operates purpose-built colocation facilities in Mesa, AZ, as well as Las Vegas, Salt Lake City, and other western markets.
• Fiberhub — Las Vegas. Its Las Vegas facility offers Tier III colocation, N+1 power with 2N available, carrier neutrality, and 24/7 engineering; the company explicitly characterizes Las Vegas as having low natural-hazard risk.
• NexusRack — Las Vegas. Offers colocation through its Las Vegas facilities and describes the area as having minimal earthquake and flood risk.

My shortlist for a DR site

I'd start with Phoenix/Chandler if your primary criterion is geological stability plus a deep colocation ecosystem. I'd then compare Las Vegas as a potentially useful geographically distinct secondary site.

One important caveat: “geologically stable region” doesn't mean “low all-hazards risk.” Arizona has significant heat, drought, water-stress and grid-related considerations; for example, current data-center risk data flags high water stress in Arizona. US Data Center Map For DR, you should evaluate the specific facility and utility feeds, not just the metro area.

For a true DR architecture, I'd also avoid putting primary and secondary sites in the same local disaster domain. A Phoenix primary with a Phoenix DR site gives excellent operational convenience but less geographic independence than Phoenix ↔ Las Vegas, Phoenix ↔ Salt Lake City, or Phoenix ↔ another suitably separated region.

If you tell me your rack count/power requirement (e.g. 5 racks/50 kW vs. 1 MW) and whether you need Tier III/IV, SOC 2/ISO 27001, HIPAA, or FedRAMP, I can narrow this to 3–5 providers and compare them on geography, redundancy, connectivity, and likely DR suitability.

Yes. For a disaster-recovery site, I’d look beyond simply “low earthquake risk” and prioritize a location that is materially different from your primary site in hazards, power grid, network routes, and weather.

Strong candidates

My shortlist for an Atlanta primary site

If your production environment is in Atlanta, I'd investigate Duffield, VA; Sioux Falls, SD; and Fargo, ND first. They're far enough away to provide meaningful geographic separation while avoiding simply putting the DR site in another Southeast market.

OnePartner in Duffield is the most directly aligned with your stated criterion because the operator specifically advertises geological stability and absence of historical natural disasters.

For a more conventional enterprise-colocation procurement, TierPoint Sioux Falls and Midco Fargo are also worth getting proposals from because their facilities have well-defined colocation, redundancy, connectivity and business-continuity capabilities.

One caveat: “geologically stable” doesn't mean “low risk from everything.” For DR due diligence I'd specifically ask each provider for FEMA flood-zone status, tornado/wind exposure, wildfire risk, seismic hazard, utility-substation configuration, generator fuel autonomy, carrier diversity, and whether the facility sits on a different power grid than your Atlanta production site.

If you tell me your rack count, power requirement, RTO/RPO, compliance requirements, and how far from Atlanta you want the site, I can narrow this to 3–5 facilities and compare them.

When setting up a disaster recovery (DR) site, choosing a location with a low risk profile for natural disasters—such as minimal seismic activity, no hurricane exposure, and safe flood elevations—is a foundational strategy.

Several prominent enterprise colocation and disaster recovery providers operate purpose-built facilities in regions recognized for geological and climate stability:

• Iron Mountain Data Centers — Operates heavily fortified, highly compliant data centers in low-risk interior and desert metros. Their campuses in Phoenix, AZ and Denver, CO are widely noted for minimal seismic activity, zero hurricane exposure, and well-managed environmental controls.
• TierPoint — Features a robust national network of over 40 data centers, with a strong footprint in the Midwestern and Central U.S. (including facilities in St. Louis, MO, Omaha, NE , and Kansas City ). These interior locations sit safely inland away from coastal storm surges, hurricanes, and active major fault lines.
• LightEdge — Specializes in compliant colocation and hybrid disaster recovery with unique underground bunker-style options in the Midwest. Notably, their Lenexa, KS facility is built 125 feet below ground in a limestone cavern, offering exceptional natural physical protection and climate stability, alongside traditional surface facilities in Des Moines, IA and Kansas City, MO.
• CoreSite — Provides geo-diverse colocation options allowing enterprises to pair primary coastal or high-risk deployments with resilient secondary facilities in stable markets like Denver, CO.

To help narrow down the best provider and region for your layout, could you tell me:

• Where is your primary production site located?
• What distance/latency requirements do you have for data replication between the sites?

When building a geo-diverse disaster recovery (DR) site, targeting a geologically stable region means looking for areas with low seismic activity (minimal earthquake risk), low risk of catastrophic flooding or hurricanes, and stable power grids.

Several prominent colocation providers and specialized facilities offer enterprise-grade space in stable continental interior or hardened underground locations:

• Iron Mountain Data Centers (Western Pennsylvania - WPA-1) : Located 220 feet underground inside a former limestone mine in northern Butler County, Pennsylvania. It offers extreme physical security and natural protection from surface weather events, tornadoes, and seismic shifts, backed by federal-grade compliance.
• Netrality Data Centers : Operates facilities across mid-country markets like Kansas City, St. Louis, Chicago, and Indianapolis. These locations provide stable continental interior positioning that avoids coastal hurricane zones and active earthquake faults while maintaining dense network connectivity.
• DataBank : Features a robust national footprint with numerous strategically dispersed Tier III/IV data centers in stable interior markets (such as Dallas and Minneapolis), allowing companies to easily pair a coastal primary site with a stable inland DR location.
• Coresite & Digital Realty : Both are massive enterprise colocation providers with multi-market portfolios. They allow you to select specific non-volatile geographic zones—such as moving workloads from high-risk earthquake or hurricane zones to stable midwest or mid-atlantic hubs—interconnected via low-latency software-defined fabrics.

If you'd like to narrow this down, let me know:

• Where is your primary production site located?
• What are your requirements for latency and distance separation?

For a disaster recovery (DR) colocation site, “geologically stable” usually means minimizing exposure to earthquakes, faults, hurricanes, flooding, tornadoes, wildfire, and sea-level risks, while still having strong fiber connectivity and power infrastructure. The best region depends on where your primary site is located (you generally want geographic separation), but several colocation providers operate facilities marketed for low natural-disaster risk.

Here are some providers and regions worth evaluating:

Regions often shortlisted for geologically resilient DR sites

• Central Virginia / Appalachian region — low earthquake risk compared with the West Coast and generally lower hurricane exposure inland.
• Central Texas (especially inland areas) — strong connectivity and fewer earthquake concerns, though flooding, severe storms, and grid resilience must be evaluated.
• Pennsylvania/Appalachian areas — some underground facilities provide additional protection against surface hazards.
• Upper Midwest (e.g., Minnesota, Wisconsin, Michigan) — generally lower seismic risk, though winter storms, tornadoes, and grid issues matter.

Questions to ask any colocation provider

1. What natural hazard studies have been performed for this facility?

   • FEMA flood zone classification
   • seismic hazard rating
   • tornado/wind rating
   • wildfire exposure
   • nearby industrial hazards

2. What are the facility protections?

   • N+1 or 2N power and cooling
   • generator fuel autonomy (72+ hours is common for DR discussions)
   • multiple fiber entrances
   • diverse carriers
   • physical security
   • SOC 2 Type II / ISO 27001 certifications where applicable

3. Is the site far enough from your primary facility? A DR site should avoid sharing the same regional disaster risks as the production site (for example, two data centers in the same earthquake zone or flood basin).

If you tell me where your primary data center is located, required latency, rack/power size, and whether you need cold/warm/hot standby, I can narrow this to specific regions and providers.

Yes. For a disaster-recovery site, I’d prioritize geographic separation from your production site plus low seismic, flood, tornado, hurricane, and wildfire exposure, rather than simply choosing a large colo market.

A few providers stand out:

My first choices

1. Duffield, VA — OnePartner ATAC
This is the most directly aligned with your stated requirement. The provider itself emphasizes the site's geological stability and lack of historical natural-disaster events.

2. Kansas City, MO — Iron Mountain KCM-1
I'd investigate this if physical protection is especially important. The underground construction provides an additional layer of resilience, while Kansas City's central location gives good geographic separation from East Coast production sites.

3. Omaha, NE — Scott Data / Nebraska Data Centers / LightEdge
Omaha is worth considering for a DR architecture because it is well removed from the major East/West Coast disaster concentrations and has multiple independent colo choices.

One important caveat: “geologically stable” doesn't mean “disaster-proof.” For a serious DR site, I'd have the provider document the site's FEMA flood zone, seismic hazard, tornado/wind exposure, wildfire risk, nearby hazardous facilities, utility-substation dependencies, carrier diversity, generator fuel autonomy, and physical separation of utility/network entrances.

If your primary site is in the Philadelphia/Camden area, I'd lean toward Duffield, VA or Omaha/Kansas City rather than another Pennsylvania/New Jersey facility. A nearby Pennsylvania colo gives excellent latency but isn't as strong a DR strategy if the regional event affects both sites.

When designing a disaster recovery (DR) site in a geologically and meteorologically stable region, organizations typically target the American Midwest, parts of the Intermountain West, or specialized underground facilities . These areas minimize risks from coastal hurricanes, active seismic faults, and major flooding.

Several prominent colocation and data center providers maintain robust footprints in these stable interior zones:

• Iron Mountain Data Centers : Famous for their ultra-secure underground facility in Butler County, Pennsylvania (housed 220 feet underground in a former limestone mine), which offers natural shielding from surface weather, temperature stability, and high seismic stability. They also operate heavily reinforced traditional facilities in regions like Phoenix, Arizona.
• TierPoint : Features a national, geographically diversified footprint with a heavy concentration of data centers in stable Tier 2 and Tier 3 markets across the U.S. Midwest and central regions (such as Missouri, Oklahoma, and Pennsylvania), avoiding high-risk coastal or active fault corridors.
• US Signal : Focuses heavily on the stable U.S. Midwest, operating enterprise-grade, secure colocation data centers in states like Michigan, Indiana, and Ohio. This region boasts a low risk for hurricanes and major earthquakes, backed by dense regional fiber.
• Netrality Data Centers : Provides strategic mid-country data center markets including Kansas City, St. Louis, Chicago, and Indianapolis. These locations offer meaningful geographic and geological separation from coastal and fault-line vulnerabilities while maintaining robust carrier-neutral connectivity.
• Flexential : Operates a wide national platform (FlexAnywhere ) with facilities spanning stable interior and non-coastal metro areas like Denver, Dallas, and Charlotte, allowing you to pair a coastal or high-risk primary site with a secure inland DR target.

If you share your primary data center location and your target Recovery Time/Point Objectives (RTO/RPO) , I can help you evaluate optimal distance spacing and specific interconnection options for your failover architecture.
