last time Tim Starling said I should ask in irc on current problems ... well, did so - no response in wikimedia-tech:

(23:52:49) Saibo: compare ;-) Seems as if purge on upload of new version fails for some old thumb versions.
(23:53:14) Saibo: note: maybe this is only from Germany
(23:53:23) Saibo: as it happened some times in the past...
(23:53:32) Saibo: squids in Amsterdam were foul

Confirmed. The 120px has an old thumb stuck.

No difference after purging to 120px (date of 121px updates).

The real 120px thumb at pmtpa:

works for me now. Same for you? From IRC: mutante had a look at it but doesn't know the root cause.

Yes, it got updated although I don't know why :)

CT told me today that the thumbnail server crashed on the 20th, so *some* of what we're seeing here may be related to that.

Per comments, this seems to be working. Since we're going to be doing a lot of work next week, we'll keep an eye out for problems in this area.
