-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Overall Cogent has been okay. We've had a few issues over the last several months. One specifically bothersome as it cropped up several times. They basically kept rewriting their CoPP ACLs and kept dropping my side of the /30 from the allow list. This caused our BGP session to start flapping. Each time this happened it took several hours to escalate to someone that understood the problem and could get it fixed. Not even referencing old tickets would help their first line of Support. On one call an engineer told me BGP was flapping because my config was split into "address-family ipv4/ipv6 unicast/multicast" rather than one big "router bgp" stanza. We have a session with AT&T, so when Cogent does something stupid, we aren't off the net... Other than bidding for a contract in a building they didn't actually have any resources, then trying to get us to pay for the costs of building out there after they won....And the sales rep quitting right after they won the RFP....they've been decent. /Ryan Greg VILLAIN wrote: | | On Jun 3, 2008, at 6:06 PM, TS Glassey wrote: |> So at one time Cogent was one of the lowest performing bandwidth |> providers.
