Schatzi, the problem appears to be at Telia's gateway link to the U.S. (hop #7). Not the actual link, but the last router before the data packets hit the U.S. link.
Dunno if they are having issues, or if the router is just being swamped.
Might send a query to your ISP about it, as they use Telia as thier Tier one transport. I would be surprised if they have not gotten a number of complaints already.
