Hello,
The following primary database masters will be switched over during the
next few weeks (more details at

Impact:
*Writes will be blocked*
*Reads will remain unaffected*
These are the concrete days, hours and affected wikis:
* s8: 10th Sept from 05:00-05:30 UTC. The affected wiki is: wikidatawiki -
tracking task: T230762

If everything goes well, we do not expect to use those 30 minutes of
read-only and rather just a few minutes.
We will email send an email the day of each failover before and after it is
done.
Sorry for any inconvenience this might cause.
