Community Relations support needed for a read-only window for s6 (frwiki, jawiki, ruwiki)
Closed, ResolvedPublic


What is the problem?

We need to failover the current s6 database primary master, to a newer host (T235469)
Technical tracking task for this maintenance: T235469
For this operation we need to set up the following wiki on read-only:


How can we help you?

We need to let users of the above wiki, that on Tue 19th November from 06:00 to 06:30 AM UTC that wiki will be on read-only. No writes will be allowed, reads will remain unaffected.

What does success look like?

Users will get notified and plan their work to avoid that maintenance window.
If everything goes fine, we expect the read-only window to last around 1-2 minutes, not 30.

What is your deadline?

We'd like to do this switchover by Tue 19th Nov at 06:00 AM UTC

I just realised that when we created this task and scheduled the maintenance I didn't take into account that we'd have had the change from CEST to CET, so I am going to update the task to reflect that this will happen at 06:00 AM UTC instead of 05:00 AM UTC.
Sorry for the confusion.
