We need to replace the current primary database master for wikidatawiki.
This host is old and out of warranty, so needs to be decommissioned. In addition, we need a host with bigger disk to be able to continue with the wb_terms table redesign (T221764).
We would need a 30 minutes read-only window for Wikidatawiki.
Date: Tue 30th July
Time: 05:00AM UTC - 05:30 AM UTC (if everything goes as planned we would not use the 30 minutes window)
Impact: All Wikidatawiki will go read-only. No edits will be allowed. Reads will not be impacted.
