s6 primary master switchover (read-only required) 19th Nov 05:00 AM UTC

Manuel Arostegui
Hello,
We have requested a 30 minutes read-only window for s6 wikis (T235475) for
the 19th Nov from 05:00-05:30 AM UTC to switchover that section primary
database master (T235469)

db1061 is an old host and out of warranty that will be decommissioned
(T217396). The new master will be db1131.

We are going to do this on Tuesday 19th Nov from 05:00 to 05:30 AM UTC (we
do not expect to use the 30 minutes window, if everything goes as expected).

Impact: Writes will be blocked on the following wikis
frwiki
jawiki
ruwiki

Reads will remain unaffected.

Communication will happen at #wikimedia-operations
If you are around at that time and want to help with the monitoring, please
join us!

Thanks
