Problem is still there.
Well, the front page still works. And firmware downloads, if you directly link to them, still work... like so:

Taking a look at the HTTP headers returned by the request, one would see that the error code returned is actually 500 (technically, Internal Server Error). Given that everything else works and given that their pages use Microsoft Active Server Pages (

), my best guess is that there's nothing wrong or overloaded with the server, but that because of some programming error or ASP misconfigruation, their ASPs are crashing, which would certainly generate a 500 error code.
