Hello,
We need to switchover x1 primary master from db1069 to db1120
https://phabricator.wikimedia.org/T226358
db1069 is a very old host that has hardware issues, it is out of warranty
and needs to be decommissioned.
Given that x1 cannot be set on read-only on a MW level, we will need to go
read-only at a MySQL level.
We are going to do this on Wednesday 3rd July at 06:00AM UTC. We expect
around 1 minute of read-only time if everything goes as expected.
Impact: Writes will be blocked. Reads will remain unaffected.
Communication will happen on #wikimedia-operations
If you are around at that time and want to help with the monitoring, please
join us!
Thanks
Manuel.
