Hi,
tomorrow (July 20th) at 15:00 UTC (08:00 PDT / 11:00 EDT / 17:00
CEST), there'll be a maintenance to the network switch which connects
the
bast1003.wikimedia.org bastion. This will interrupt network links
(and thus your SSH connections over that bastion server) for up to a
minute.
If you're accessing a Wikimedia production server over
bast1003.wikimedia.org around that time, please switch your SSH client
config to use e.g.
bast2002.wikimedia.org (which will be unaffected).
The Phabricator task for this network maintenance is
https://phabricator.wikimedia.org/T286069
Cheers,
Moritz
