WashingtonPost.com busted - returning 504

Going to http://washingtonpost.com (and having it redirect to https) yeilds a 504 with the response:

---

An error occurred while processing your request.

Reference #97.7c0d0317.1356663462.746961a

Headers: Connection keep-alive Content-Length 175 Content-Type text/html Date Fri, 28 Dec 2012 03:03:08 GMT Expires Fri, 28 Dec 2012 03:03:08 GMT MIME-Version 1.0 Server AkamaiGHost Vary Accept-Encoding

To avoid the problem, I've added a boolean config property: extensions.https_everywhere.washingtonpost.com = false

I'm using FF 16.02 on OSX 10.5.8.
