Hello,
We have requested a 30 minutes read-only window for s8 (wikidata) for the 30th July from 05:00-05:30 UTC to switchover our primary wikidata database master (T227063)

db1071 is an old host and out of warranty that will be decommissioned (T217396).
This will also unblock some migration stages of the new redesign for the wb_terms table (T221764)

We are going to do this on Tuesday 30th July 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, 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
