Objectively, provably false.

TTFN,

One in the AM "..caused by a power outage in a vendor data center where Cogent is collocated." They went on to have another outage at around 9:30 PM on the same day for which I'm still waiting for an RFO. During this outage, they still were advertising our BGP routes so we didn't fail over to our 2nd provider. I notice that happens alot with them. When they go down, they still advertise your routes.

I've never had a big issue with the two working with each other. The only issue we had is I suspected we weren't getting as much bandwidth as we paid for. They had to work out where the policer and/or bottle neck was. This is the only issue we had in 5 years with this set up and it got resolved. IME, when there is a full outage, it's always been clear who the responsible party is.
