swell in the utility feeds powering one of the Azure data centers in
San Antonio, Texas, that overwhelmed the facility’s surge suppressors,
knocking out its cooling systems. The “load-dependent thermal buffer”
baked into the cooling system for such occasions was eventually
depleted. Air temperature inside rose, triggering automatic shutdown of
hardware.

A hydrogen explosion occurred in an Uninterruptible Power Source (UPS) battery room. The explosion blew a 400 ft2 hole in the roof, collapsed numerous walls and ceilings throughout the building, and significantly damaged a large portion of the 50,000 ft2 building. Fortunately, the computer/data center was vacant at the time and there were no injuries. Read more about the explosion over at hydrogen tools here .
