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.

@Marostegui friendly reminder to ping one of us personally to make sure last minute things are noticed ;) Best of luck with the read-only!

The banner has the wrong date, it says 21st May and points to T251982: Upgrade and restart s1 (enwiki) primary database master: Thu 21th May
