[SAC] [Hosting] Power issues this morning

[Lance Albertson]

All,

I wanted to send an update for the power issues from this morning. I
investigated the hosts that lost power and discovered one of them had a bad
PSU and lost all power when the other good PSU lost power (I replaced it
this morning). There were other hosts that had their power not properly
split between the two power feeds which I have since fixed. Other hosts
that were affected are racked in a part of the datacenter that only has one
power feed.

I'm still waiting to hear why that particular power feed completely lost
power instead of the UPS holding power.

Thanks-
