Later today (starting in a few hours around 18:00 UTC) we'll be
rearranging the puppetmaster setup for most cloud VMs[0]. No tools or
services (other than puppet) should be affected, but some of you might
get grumpy emails about broken puppet runs during the transition, which
I encourage you to ignore. If you're planning to update the puppet
configuration of your VMs, I encourage you to postpone that work until
after our migration.
