I was looking at my old posts from six years ago when I noticed that a lot of them seem to be broken. The pictures just won't load and opening them in a separate tab always yields "Error 502: Bad gateway". I also saw this in quite a few other soups.
For the majority of posts this means that only the small
"preview" picture is broken. Removing the last bit of the filename in the pictures URL (
e. g. http://asset-a.soupcdn.com/asset/1647/0191_a782_690.jpeg to
http://asset-a.soupcdn.com/asset/1647/0191_a782.jpeg) will show the full size picture and thus could be used to restore the corrupted posts. I might write a python script for that later...
