Hello, We have requested a 30 minutes read-only window for s1 (enwiki) (T234801) for the 14th November from 05:00-05:30 AM UTC to switchover that section primary database master (T234800) db1067 is an old host and out of warranty that will be decommissioned (T217396). The new master will be db1083 We are going to do this on Thursday 14th 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 wiki: enwiki 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
