s7 primary master switchover (read-only required) 26th Nov 06:00 AM UTC

Manuel Arostegui
Hello,
We have requested a 30 minutes read-only window for s7 (T238046) for the
26th November from 06:00-06:30 AM UTC to switchover that section primary
database master (T238044)

db1062 is an old host and out of warranty that will be decommissioned
(T217396). The new master will be db1086

We are going to do this on Tuesday 26th Nov from 06:00 to 06:30 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:
arwiki
cawiki
eswiki
fawiki
frwiktionary
hewiki
huwiki
kowiki
metawiki
rowiki
ukwiki
viwiki

Reads will remain unaffected.

This also includes centralauth database, which means some operations might
fail during the read-only period, such as: GlobalRenames,
Changing/Confirming emails, logging into new wikis, password changes...

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

Thanks
