I need to migrate one of our static content virtual servers before the end of the day tomorrow (18 March 2012) or it's going to get migrated without me. So, I'm going to schedule the process instead of having it just happen.
The migration process apparently takes about 30 minutes, but I'm going to do a backup while the server is down, too. So expect about 60 minutes for the process.
Some StatusNet sites will remain up during the downtime.
Update (10:19AM EDT): sites are down now.
Update (10:33AM EDT): backing up the static server.
