To be more specific, in case anyone knows a possible solution; He tried three different computers in his own household. He tried removing the router and connecting the computer directly through the modem. The site works at his friends house which is in the same neighbourhood if I'm not mistaken. Also, every other website works for him. It's only StreetHop that doesn't work, no matter what he does, and only from his household. I don't know if he actually called his ISP to see if there was a problem with his specific line (in Norway DSL is customary, not cable, and I'm not sure how the cable thing works. Internet through the coax lol?) and if he hasn't he should try that. But there is no logic behind the problem it seems.
