Dear Wikitechians,
Dear colleagues,

to be available for reading as usual. Users saw

It's a bit complicated.
When SRE sets the read-only mark, they start counting from that time and it

You should probably just file a bug.
Its certainly plausible it had something to do with data center switch, but
it could just as equally be unrelated. It requires someone to investigate
what part of the system failed (job queue? Varnish? Swift?) which would
then lead to a root cause. Its pretty i

will be a switchover from our secondary data center in Texas back to the
primary data center in Virginia. That day, starting at *14:00 UTC*, there
will be a brief (just a few minutes) read-only period for al
