have you banned any Swedish networks?
I have even tried different servers from my VPN in Holland and Sweden.
In Slovenia, gambling sites without government approval (such as bwin, bet-at-home) are banned at the DNS level. I've noticed that from this week, satoshidice and just-dice are banned too (DNS doesn't resolve). Changing my DNS servers to Google's 8.8.8.8 bypasses this.
as I edited in my post just after you answered, it seems to be my computer that´s the problem. (could access from a different computer). The connection to just-dice died last night and I have tried both Firefox and IE (and now also chrome) but
edit: all the other websites I visit works just fine.
