After today's (2016-04-19) datacenter switchover test [1] a configuration issue resulted in edits not appearing on Special:RecentChanges for about 20 minutes (14:48 - 15:10 UTC) [2].

The recent changes entries have now been restored, but since they're several hours old, they may no longer appear on the main Special:RecentChanges – and since no one was able to see them earlier, there are probably some edits that need reverting and articles that need deleting hidden there.
It would be great if someone could review them. To do it, view a page like this (substitute "commons.wikimedia.org" with your wiki):
…scroll to the bottom, and look at the changes in the affected period (14:48 - 15:10 UTC).
Thanks and sorry for the issue!
(FlaggedRevs was not affected, and wikis using it are probably fine.)
(On very active wikis, like English Wikipedia, this might already be outside of the limit that Special:RecentChanges can display…)
