(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
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
