Description Bawolff (Brian Wolff) 2013-08-12 03:18:50 UTC 
When viewing Special:newfiles on commons, lots of thumbs don't render. Looking at the requests, the affected files all have same error message:

<html><head><title>Error generating thumbnail</title></head>
<body>
<h1>Error generating thumbnail</h1>
<p>
Error creating thumbnail: 
</p>
<!-- http://commons.wikimedia.org/w/thumb_handler.php/e/e0/2004-12-01_500-Millibar_Height_Contour_Map_NOAA.png/120px-2004-12-01_500-Millibar_Height_Contour_Map_NOAA.png -->
<!-- mw1153 -->

</body>
</html>

When visiting the url a second time, the file renders (and is cached). I would guess the request is being routed to a different backend server, and there's just something wrong with mw1153.
Comment 1 jeremyb 2013-08-12 03:24:06 UTC 
confirmed, happened to me a number of times and the 2 times I actually got a backend listed (rather than empty body because I guess it didn't like my Accept header) it was mw1153
Comment 3 jeremyb 2013-08-12 04:11:10 UTC 
mw1153 should be fixed since sometime before 04:00 UTC.

If anyone's still seeing image scaling (thumbnailing) issues please reopen.
