Thumbnails seem to be broken on uk.wikimedia.org such as at http://uk.wikimedia.org/wiki/File:WMUK_AGM_2009_Attendees.jpg. Calls to http://upload.wikimedia.org/wikimedia/uk/thumb/6/6c/WMUK_AGM_2009_Attendees.jpg/800px-WMUK_AGM_2009_Attendees.jpg are rejected as errors.
The error message is >The requested URL /w/thumb.php was not found on this server. > >Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request. And in fact the same error is returned on http://uk.wikimedia.org/w/thumb.php
Thumb scripts look like it should be passing to the correct hostname on the backend... (tools/upload-scripts/thumb-handler.php) Rob, can you confirm that the image scaling cluster boxes have up to date Apache config files and common-local dirs? They may be missing the ukwikimedia docroot subdir or something.
The image rending cluster was not included in the batch updates to the apache cluster. We will have to take some steps on the operations end to remedy this in an automated fashion in the future. For now, I manually updated the image rendering servers and the thumbnail generation now appears to be functioning normally.
