The Wikimedia datacenter team will be performing some routine network
maintenance next Wednesday. This will cause brief, rolling network
interruptions for essentially all tools, services, and virtual servers
-- each physical server will be briefly unplugged as its network cable
is moved to a new switch. Ideally these interruptions will only last a
few seconds and be unnoticeable, but downtime may be longer if there are
This process will begin at 14:00 UTC on Wednesday the 24th, which is 7
AM in California. All moves should be completed within an hour.
