TLDR:
- Instead of `*.db.svc.eqiad.wmflabs` use `*.db.svc.wikimedia.cloud` to use
the new replicas
- Quarry will migrate March 23 to use the new cluster
- In a ~month (April 15) the old cluster will start retiring. See

Hi everyone,
I'm happy to announce that the new replicas cluster is available for use
after a few weeks open for testing.
To use the new cluster, you will only need to change the hostname when
connecting to the databases. Instead of `*.db.svc.eqiad.wmflabs` you can
use `*.db.svc.wikimedia.cloud`. See:

This brings us to the timeline updates:
https://wikitech.wikimedia.org/wiki/News/Wiki_Replicas_2020_Redesign#Timeli…
- March 2021
- Announce new cluster domains for all users - March 12
- Migrate Quarry to use the new cluster - March 23
- April 2021
- PAWS migration - Estimated first week of April
- Migrate the old cluster to utilize new replication hosts. Replication
may stop. - April 15
- Redirect old hostnames to the new cluster - April 28
Quarry is ready so it will transition first to use the new replicas. This
will happen on March 23, at which point we will deploy the changes and
update the docs. We are publishing a note on Tech news but if there are
other venues where this information would be useful please help us spread
the word.
PAWS is in the process of being migrated. We estimate it could be ready to
use the new cluster at the beginning of April, and will publish more
details as soon as we know.
On April 15 the old cluster will be moved under the new replication hosts,
at which point there may be side effects and replication may stop.
We recommend you update your code earlier to use the new hostnames to
verify things are working normally.
Not long after, the old hostnames (`*.db.svc.eqiad.wmflabs`) will be
redirected to the new ones (`*.db.svc.wikimedia.cloud`), at which point the
old cluster will effectively be inaccessible.
If you have questions or need help please reply to cloud(a)lists.wikimedia.org,
join the #wikimedia-cloud IRC channel, or open a ticket in Phabricator with
the Data-Services tag.
Thanks,
