The register holds 74 data centre UPS and battery room entries from public reporting, 2010 to 2026, in 25 countries. 31 of them are fires or thermal events; the rest are electrical, mechanical, control system and other incidents. Each entry lists its sources.
Where the public reporting names a part, the most common are UPS and battery rooms (74), backup generators (25), switchgear and electrical rooms (12). 0 of the 74 entries name no part. The register does not guess a cause; where a fire service, regulator or the operator states one, the entry carries it and says who said it.
In the reporting the register has found, United States (14), United Kingdom (9), South Korea (8) have the most entries. 9 are in the United Kingdom. That partly reflects where the assets are built and where the press reports on them.
