Re: [Wikitech-l] s3 primary db master failover on Thursday 17th January 07:00 AM UTC

Hello, Due to the recent issues with the PDUs on both A2 (T213748) and A3 (T213859) we need to swap s3 db primary master (T213858), as it lives on A2. We are going to do this on Thursday 17th at 07:00 AM UTC, and we have requested a 30 minutes window (T213864) 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: 07:00AM UTC - 07:30 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
