phabricator maintenance

Hi everyone,

phabricator migration to new VM is now complete, but it experiences performances problems because it's still re-importing all the repositories and, given there's a kernel fork there, it takes a long time. It's borderline usable now, but sometimes it fails to load its CSS on first attempt, and sometimes it just takes a long time to respond. Sorry for the inconvenience!

One repository import is complete, we'll need to do some more maintenance on the network at that site, but it's not going to take as long. Then this will hopefully be over and things will get back to normal.
