Interesting. I have a server hosted on Bell Canada's network and I saw an outage of about 30 minutes today, but it ONLY affected connections from Verizon's network. This includes my own FIOS connection. I still could connect to the server through Comcast, Level 3 and XO with no problems. Traceroutes from my Verizon IP only got 2 hops, stopping at a philly router and traceroutes back to the same IP from that server got as far as NYC.
