Emergency read-only time for s4 (commonswiki)
Closed, ResolvedPublic

Description

Due to HW failure on the commonswiki primary database master, we need to failover this host to another one.
We'll do that Friday 29th May at 05:00 AM UTC
We'll need to set commonswiki on read-only time for around 30 minutes (hopefully just a few minutes), while writes cannot go through but reads will remain unaffected.

There's no time to distribute Tech News before the fact, due to the emergency nature of the read-only window (the next issue goes out on Monday), but I've posted a notice on the Commons (English) Village Pump to give some warning to the Commons community.
