It seems a single power circuit in our facility has failed, bringing down a few dedicated servers.
Be aware that we do offer the option to order dedicated servers with redundant power supplies, fed by different power circuits.
Update: about 25 dedicated servers were affected by this. The power circuit was replaced within 15 minutes by one of our electricians.
This is a very rare event. It has only happened three times in our fourteen year history.
Some stats: all our servers are powered by almost 400 208V power circuits, 20 and 30 amps each.
