Ottix.net, the local IX is now back online. There were cable issues at 250 Albert Street (broiled in politics), and they have finally been resolved. It took 6 months to have 6" of fibre connected.
This means that traffic to other Ottawa ISPs and the like may in fact stay in Ottawa as various ISPs reconnect. So far, NRC, CRC, Agriculture Canada, and the F.root-server.net are reachable:
cod-[~] mcr 1007 %mtr -4 -r ftp.nrc.ca HOST: cod.sandelman.ca Loss% Snt Last Avg Best Wrst StDev
- oceania.cooperix.net 0.0% 10 0.2 1.0 0.2 8.5 2.6
(note that ftp.nrc.ca is also reachable over IPv6, using a much longer route that unfortunately goes via Japan. This will be resolved very soon)
I hope that other ISPs will soon reconnect.
