This is the main tracking task for the multiple read-only windows we'll need in the following weeks.

The reason and duration of the read only windows are the same:

Reason: We need to upgrade and restart our primary database masters
Impact: The wikis listed on each subtask will not be able to receive edits - reads will remain unaffected at all times.
Duration: We expect the real read-only to take around 45-60 seconds although we'll request a 15 minutes read-only window just in case.
Date and hour: Each subtask will include the date and hour of the maintenance.
Affected wikis: Will be on each subtask. We'll probably group sections, so we don't have to request 8 read-only windows, but maybe 4 instead.

Please let me know if further information is required
