Ahhh sorry about the 504s! You should be able to retry if it's giving you issues. We only have 4 gunicorn workers running on a single Linode right now, we'll try to bump it up to 6-8 to see if that helps in the meantime.
edit: Increased the worker count to 8. Hopefully that helps a little bit.
So, i'm pretty disappointed that you took an article posted on FireDogLake (http://dissenter.firedoglake.com/2013/05/29/imprisoned-cia-t... ), simply pulled the PDF and the text which they transcribed by hand, rehosted it yourself, and then posted it to HN.
Especially since you did it without any citation/reference (and since FDL notes that they did the legwork on this).
Edit: I'm going to give the OpenWatch guys the benefit of the doubt, and assume that they never saw the FireDogLake post, and that they were linked directly to the PDF of the letter that is hosted on DocumentCloud's S3 account.
It would be nice if they acknowledged the original source of the letter.

edit2: Turned on memcache.
