I called my ISP (COGECO) in Canada, and I got some foreigner. I asked him if There were any blocks in place, and he said no. Bull. I called back and got a regular I talk to there, and He said that they have been blocking ports 6346-9999. I asked him since when, i was DL'ing yesterday, and he said since 2 AM this morning. But, I did get him to unblock me, for how long i don't know.
