FYI - Suspension of Cogent access to ARIN Whois

Tue Jan 7 22:54:22 UTC 2020

The part that has me uneasy about that action is that the chance that Cogent sales reps are using Cogent IPs is probably low. They're probably doing this work at home. They wouldn't be blocked at all. 

Also, the chance that there are people that wish to use ARIN Whois services that are not Cogent employees and yet come from Cogent IP space is quite high. They would be blocked and yet, didn't do anything. 

That said, if there's a stern warning about Cogent abusing the system, maybe their customers finding out is a good thing for the overall community. ;-)

As noted earlier, ARIN has suspended service for all Cogent-registered IP address blocks - this is being done as a discrete IP block access list applied to relevant ARIN Whois services, so the routing of the blocks are immaterial - a customer using a suballocation of Cogent space could be affected but customers with their own IP blocks blocks that are simply being routed by Cogent are not affected.

This is a disproportionate response IMHO. $0.02 

YMMV,

Seems entirely reasonable to me. You break the rules, you lose the privilege. Works the same way with my 7 year old.
