Betreff: [Wikitech-l] Gerrit downtime this Monday!
Hi,
So the time is upon us to finally upgrade Gerrit. I thank everyone in advance for all of
your patience and good work testing things out for us. The plan is outlined in detail on
Phabricator[0], but I'll give everyone the short version here.
The downtime will be on Monday, July 25th from 01:00 to 04:00 UTC; that's Sunday night
for those of us who are US-based. This time was picked based because it's one of our
lowest traffic times on Gerrit. There's never a *good* time to bring it down, it's
always being used, but this looks like it'll impact the fewest number of users. I do
not anticipate the process actually taking the full 3 hours, but I'm giving us a lot
of extra time just in case.
Jaime will be on hand to assist with a final DB snapshot of the old version and possible
rollback, and Daniel Z. is going to assist me with the puppet work. Most of this is
already prepared so the amount of "change" to do the swap has been kept to a
minimum.
Gerrit is a critical service to all developers, so the plan includes a generous provision
to roll back if things are not operating properly--I'd rather us be on the old version
that works on a Monday morning than be stuck broken going into the work week.
I'll be sure to send a last minute reminder Sunday night prior to taking services
offline.
Thanks again!
-Chad
