Looks like https://meta.wikimedia.org/w/index.php?title=Logo_selection_procedure&diff=5524801&oldid=5524353 is the corresponding change (exactly the same time, very similar change message) which was done by Maggie.

Maggie: Did you do anything special when moving, which might have made edits appear as 127.0.0.1?

appear as 127.0.0.1?

Special? No. It asked if I wanted subpages moved, and I clicked yes. :)

I suspect this is the translate extension's fault since the pages in question is translatable. (Although it may just be a coincidence)

I noticed the same in twn today:

[13:01:15] rakkaudella> [[MediaWiki:Passwordreset-text-many/qqq]] !NB https://translatewiki.net/w/i.php?oldid=4753834&rcid=8103964 * 127.0.0.1 * (+148) Importing a new translation

I don't remember having done any changes here.

It's likely something merged between 2013-05-31 14:19:23 +0000 and 2013-06-03 09:57:40.

https://gerrit.wikimedia.org/r/#/c/65447 looks likely cause.

Those patches should fix everything except the issue actually reported.

That file needs revert, because of bug 49086 which I just filed.

Bumping criticality, given this touches deletions.

Yes, and they don't even show up in logs for either 127.0.0.1 or FuzzyBot.

See the newer post on https://meta.wikimedia.org/wiki/Meta:Babel#Special:Contributions.2F127.0.0.1

Doesn't fit the definition of critical. Will commit a "fix" for the last file now.

My reading of comment 11 and comment 12 is that deletions (in addition to moves) are having an issue, possibly involving data loss.

It only affect moves and deletions of translatable pages. And there is no significant data loss - some events are logged to wrong place etc.

Further suggesting that this is related to the translate extension, after http://www.wikidata.org/wiki/Special:Contributions/127.0.0.1, FuzzyBot failed to automatically mark http://www.wikidata.org/wiki/Template:Recentchanges/text/en as patrolled (and yes, to state the obvious, the bot rights on Wikidata *do* include autopatrol). Note that this was just 4 minutes after the localhost page moves.

I'm noting that https://gerrit.wikimedia.org/r/#/c/67247/ is still waiting for review and did not get into 1.22wmf6, while the three other patches did.
