Our hosting company just let us know of a power issue which needs some work tonight.
The physical systems will be down from 3am to 6:30am CET and will impact at least bugzilla, web, CI OBS and some email. I'll also do a couple of trial reboots of the server this evening which should only cause brief outages (<5min) but may reveal other problems. Updates on #mer David -- "Don't worry, you'll be fine; I saw it work in a cartoon once..."
