Cogent's best friend to the rescue: http://bgp.he.net/ip/104.31.18.30#_dns Looks like mostly proxy/torrent sites on that IP address. -- Jason Canady Unlimited Net, LLC Responsive, Reliable, Secure On 2/11/17 5:11 PM, Marco Teixeira wrote:
So... i doubt CloudFlare allocates one ip per domain served... which means Cogent customers will be unable to access other CloudFlare proxied site, served by this same IP, for a particular geographic zone? --- Marco On Sat, Feb 11, 2017 at 8:44 PM, Alistair Mackenzie <magicsata () gmail com> wrote:Cogent confirmed on the phone that they are the ones who put the blackhole in place. This is after they closed our ticket twice without response. Purposely didn't mention a website in the ticket yet they asked on the phone if it was regarding thepiratebay so they are very aware of this...

Someone else got back: "Abuse cannot not provide you a list of websites that may be encountering reduced visibility via Cogent" I almost wish I had a Cogent circuit just to bring this up with an account rep. Almost. I'd very much so view this as a contractual violation on Cogent'spart.Cogent keeps contacting me every year wanting to sell me service. This will be a good one to bring up when they call me next time. -- Brielle Bruns The Summit Open Source Development Group http://www.sosdg.org / http://www.ahbl.org
