Last night, around 11:30pm, the power went out in my apartment building and the ones on either side. I know this because the five UPS units around my place all started screaming immediately. There are enough of them to give me about 10 minutes to cleanly shut down the servers, which I did, but not before texting the local power company to report it. They had it on again at 1:15am, just after I'd fallen asleep. I finally got to bed around 2 after bringing all the servers back online, rebooting my desktop computer, and checking to make sure no disk drives died horribly in the outage.
But unlike the last time I lost power, this time I did not lose email, issue tracking, this blog, everyone else's site I'm hosting, or the bulk of my active source control repositories. That's because they're all in the cloud now. (I'm still setting up Mercurial repositories on my Azure VM, but I had moved all of the really important ones to Mercurial earlier in the evening.)
So, really, only Weather Now remains in the Inner Drive Technology Worldwide Data Center, and after last night's events, I am even more keen to get it up to the Azure VM. Then, with only some routers and my domain controller running on a UPS that can go four hours with that load, a power outage will have less chance of waking me up in the middle of the night.
