What's up with VZW
blacklisting a large amount of IP space on their MXes? I have tried sending mail
to
verizonwireless.com from
several boxes on Cogent's network to no avail... Is Cogent on the "bad boy list"
yet again? Anyone have a useful contact there? We're not able to correspond with
our sales rep via email and they're losing business. I have contacted some NOC
engineers with no luck...
Trying 162.115.163.69...
