Hello,
We need to upgrade the operating system on the server hosting the CI systems (Zuul, Jenkins). We will switch the services from contint1001 (eqiad) to contint2001 (codfw) which has been upgraded to Buster.
The maintenance is scheduled for Monday May 11st 14:00 CEST (12:00 UTC), just after the European SWAT window.
The maintenance window is TWO HOURS, but probably the switch will be complete in a shorter time frame.
During the maintenance, CI will not be available: no tests will be run and events (code-review +2, rebase, new patchsets) will not be captured.
The beta cluster will NOT be automatically updated.
If a change has to happen on the configuration repositories:
* operations/puppet : locally run: bundle update && bundle exec rake test * operations/mediawiki-config : locally run: composer install && composer test
Then manually V+2 and Submit the change.
After the maintenance, Antoine will retrigger most events.

Synchronization will happen on IRC in #wikimedia-operations
Later we will switch back from contint2001 to contint1001. The goal is to get rid of jessie servers and run fully on buster.
cheers,
