Never attribute to malice that which is adequately explained by stupidity?

This looks pretty intentional to me. From http://www.cogentco.com/en/network/looking-glass : 
BGP routing table entry for 104.31.18.30/32 , version 611495773
Paths: (1 available, best #1, table Default-IP-Routing-Table)
  Local
    10.255.255.255 (metric 10177050) from 154.54.66.21 (154.54.66.21)
      Origin IGP, metric 0, localpref 150, valid, internal, best

Call it a "hunch" but I doubt 10.255.255.255 is a valid next-hop router.

Funny. 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's part. 

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.
