This was my problem too (Virgin) and the reason I changed to bethere just
before Christmas. I was getting more and more routing failures during/after
heavy JOSM usage especially which would lock me out (usually for 30 mins or
so) from all JANET domains. Since changing ISP I have had no problems.
Virgin also appeared to be closing off other port addresses so that I was
getting increasing problems routing back to some ports on my home network
via the net.
