Hi everyone.

We have some updates related to T260389 Redesign and rebuild the wikireplicas service using a multi-instance architecture https://phabricator.wikimedia.org/T260389.

The new cluster will be ready for testing on February 1st, and we need your help.

Please subscribe and comment on T272523 Early testing of the multi-instance architecture https://phabricator.wikimedia.org/T272523 or reach out if you would like to help test it by migrating your code. We want to closely monitor it and tune it as we ramp up usage.

PAWS and Quarry will migrate to use the new cluster later in February, we will publish more information as soon as possible.

The old cluster will remain available in parallel during the migration.

Thank you for your help,
