Re: A surge
Quite possibly a bad configuration on their servers and AC which meant that once power resumed they all automatically started up again rather than a phased start up.
All those motors, fans and spinning disks might have drawn too much current all at once causing the failsafes to kick in. This might have been interpreted as the power not stable/another outage and then not resumed until they figured it out later.
Just a guess...
