Single homed on Cogent.* is a problem. Their network is known for being cheap, not resilient. Last time I was involved in a Cogent install for a customer, all of their distribution devices connected to a SINGLE core at a major south-central US carrier hotel. True device redundancy required a wave to another building. Pretty of absurd IMO for a carrier that likes to play “holier than thou” with peering.
