Hello,
Due to hardware malfunction on the current s3 database primary master (T219115) we need to failover it to a different host.
We are going to do this on Thursday 10th at 05:00 AM UTC, and we have requested a 30 minutes window (T220080) as we have to go read only for all the wikis living on s3 (P7994).
Impact: Writes will be blocked, reads will remain unaffected. Time: 05:00AM UTC - 05:30 AM UTC (we do not expect to use the full 30 minutes window).
Communication will happen at #wikimedia-operations If you are around at that time and want to help with the monitoring, please join us!
Thanks
