Cogent for ISP bandwidth

I appreciate the reference to bgp.he.net, I had not used that tool before.

We've worked with Sprint for years, and they have always been excellent 
for reliability and support. We recently picked up Level3, and so far 
they have been very good as well. It's a small thing, maybe, but I like 
that both Sprint and Level3 have nice online tools for change requests, 
trouble tickets, etc... We've been a Lightcore/CenturyLink customer for 
years as well, also very reliable. They don't have the slick online 
tools, but I can usually get a live person in their NOC.

Cogent is being very aggressive with their pricing, and if it weren't 
for the fact that we are geographically challenged and have to pay for 
transport to get to them, we might have already taken them up on it.

Thanks for all the input from everyone.
