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
