Database primary master failover on s4 (commonswiki)
Open, HighPublic

Description

We need to replace the current primary database master for Commonswiki.
This host is old and out of warranty, so needs to be decommissioned.

We would need a 15 minutes read-only window for Commonswiki.

Date: Tue 26th January
Time: 07:00AM UTC - 07:15 AM UTC (if everything goes as planned we would not use the 15 minutes window)

Impact: Commonswiki will go read-only. No edits/uploads will be allowed. Reads will not be impacted.

Trizek-WMF moved this task from To Triage to In current Tech/News draft on the User-notice board.

I included it in the two next issues of Tech News.

I'm going to inform the community soon, on VIllage Pumps and using the Watchlist notice.

A banner will be setup as usual, visible 30 minutes before the start time on Commons.

Message sent to the VP and posted on the Watchlist notice. I will setup the banner next week.
