Added a start time.
[[Gamepedia]] will be upgraded to '''MediaWiki version 1.33''' on Tuesday December 10th 2019. We will have rolling read-only time as we upgrade each wiki, which will take an hour per wiki at most. Starting on Monday December 2nd 2019 we will begin the [[mw:Actor migration|actor table migration]] in the background. This should have no impact to users, though due to the database load may cause page saves to take a bit longer. Doing these migrations prior to the upgrade will enable us to greatly reduce the read-only time needed during the upgrade.
