This Sunday (May 13), we're planning to do some of the pending migration of osmocom.org services from our old server to a new machine.
This will cause some downtime. Hopefully it will be minimal, but for sure there will be unexpected events that will mean some of the osmocom.org services will be unavailable at some point during Sunday :/
In terms of priorities, gerrit is high up on the list, so this is the primary focus. If that goes well, redmine is the next on the list.
In case you're interested in the gory details, #3076 is the overview ticket.
