At 3:42 PM this afternoon one of the UPSes that supplies power to our Santa Rosa data center had it’s load disconnected during routine maintenance. Power was restored to approximately 3 minutes later at 3:45 PM. The affected UPS handles both our own internal loads as well as our colocated customers. The overwhelming majority of our systems are supplied with redundant power fed from two independent power systems and no public services experienced anything more than a transient failure. More information will be forthcoming once our internal investigation of the procedural failure has completed. – Kelsey
