Hey there,

Since Sunday I've noticed YouTube refuses to load over our Orcon unlimited connection. Currently we're using a Genius Lite in front of a network of AirPort Extremes. Connecting directly to the Genius doesn't make any difference. I use primarily Safari on OS X, but it's happening on our Windows machines and iPhones too, as well in Chrome and Firefox.

The strange thing is that the DNS entries are coming back fine and I can traceroute and ping youtube.com just fine. Tunneling over SSH also works fine. The only thing that I could possibly think of is that we've switched to the Orcon supplied modem over the Dynalink one we've been using before.

Tried calling Orcon about this issue as well as our lack of phone line/dial tone despite paying for a phone and the CSR refused to open a ticket for this until the phone line dial tone issue was sorted out. He mentioned that could also be the cause of our slow speeds, I'm not an ADSL expert so I'm not sure how much truth there is to that.

The strange thing is that if I telnet to youtube and do a manual HTTP request, it brings back the page just fine. As such I'm at a loss as to what it could be. Other sites work just fine (to my knowledge). I'm going to try swap the modems out again and see if that changes anything.

Any other ideas? The flatmates are bugging the resident IT guy and he is at a loss :(
