[Clusterusers] Another power blip at 4:20PM

[Wm. Josiah Erikson]

Please do! I've been UPSing all kinds of things all over campus. I now 
have UPSes underneath every piece of networking equipment in ASH except 
the switch underneath your desk, also the first floor of Cole and the 
head node of the Film/Photo building...

They were on campus today, and I was asked for a full list of when and where these were occurring, which I provided, and they are looking into it. They're unaware of any issues - so as of now, it still seems that nobody knows why this is happening.
