Due to a lucky arrangement of schedules, we are going to move the deployment-prep project to the new Cloud region this week, starting in a few minutes. *This includes all of the infrastructure behind the beta.wmflabs.org site.*
Various people will be standing by to troubleshoot the outages that result, but for the most part if you see bad behaviors you should disregard or work around them for the time being.
Once everything is moved and semi-stable I will send a followup email, at which point the deployment-prep team will once again become interested in bug reports :)
Sorry for the short notice! With a little luck this should be mostly painless.
