One shared, company-wide contact — not tied to any one specific facility below.

Facility location(s) — the physical data center's location, not your company headquarters or a sales office. A company HQ and its actual facility can be in different countries.

A second facility can be in an entirely different country or state — each one gets its own full location, not just a city.

Disclaimer: This page was compiled with a structured research and verification process from publicly available sources. A human decides whether each page is published, but individual facts — addresses, contact details, and whether a company operates in a given location — are not independently fact-checked by us. Where you see a “Verified” badge, it means multiple independent sources agreed, not that we personally confirmed it. Companies open, close, relocate, and change contact details without always updating public records, so treat everything here as a starting point, not a confirmed source. If you're making a business decision, verify directly with the provider. Notice something outdated or incorrect? You're welcome to let us know — this site is updated periodically.
