When I try to access http://news.ycombinator.com on my computer, I get
502 proxy error: Proxy Error The proxy server received an invalid response from an upstream server. The proxy server could not handle the request GET /. Reason: Error reading from remote server
This happens in all browsers (even wget on the command line results in
HTTP request sent, awaiting response... No data received.).
All other URLs work fine, ping works fine and seems to resolve to the correct IP

At first I thought Hacker News was down, but then I realized it works on other people's computers. I am able to get to the listings from hckrnews.com (which even has a nicer interface), but cannot access any of the comments.
I am the only one with access to my computer. I then thought it might be a Chrome plugin, but given that it happens in all browsers, and wget, that can't be it.
