Cogent for ISP bandwidth

I use Cogent as one of our upstreams at work, and I'll basically 
reiterate what others have said -- overall, I'd have no problems 
recommending them.   Their routing can sometimes be a little weird 
(though this is MUCH better now than it was a couple of years ago), so I 
wouldn't necessarily use them as my main provider for latency-sensitive 
applications, but this isn't normally a problem with 'general' 
traffic.    The A peer/B peer stuff they used to do was definitely 
weird, but they migrated us away from that configuration a few months 
ago (peering with them out of TorIX).   Presumably they're doing that 
across the rest of their network.   Their support has been fantastic in 
my experience..

I'd have to say they're probably the least painful provider I've dealt 
with overall (unlike some providers *cough*Telus*cough* who I've been 
waiting 7 weeks for to set up a freaking BGP session...).   I'd have no 
problems picking Cogent as a provider, though of course as one of many 
providers for redundancy (which would be no different than any other 
single provider).
