I'm still having the same issue.

If I try to go to either channel with Firefox I get a 503 error.

I've installed User-Agent Switcher in Firefox, and I can get into either channel by changing the User-Agent to Chrome, Opera, IE and even Safari.

This might be caused by a configuration in the server. As I can access all the functionality while identifying as a different browser.

After updating my Firefox to version 31 ESR (I was on version 28). The page works again.
It looks like the server is directing to an invalid page for a user-agent that doesn't understands.
