Hi,<br><div style="direction: ltr;"><br>&nbsp;&nbsp;&nbsp;&nbsp; What's up with VZW blacklisting a large amount of IP space on their MXes? I have tried sending mail to <a href="http://verizonwireless.com" target="_blank" onclick="return top.js.OpenExtLink(window,event,this)">
verizonwireless.com</a> from several boxes on Cogent's network to no avail... Is Cogent on the &quot;bad boy list&quot; 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...
