All,<br><br>I knew I should have checked this list before opening tickets far and wide. I've been experiencing this issue since before 5:30pm EST and just wanted to report that ICMP *IS* affected for me, but only for certain IP addresses. TCP seems to be intermittently affected.<br>

<span style="font-size:11pt;font-family:Calibri,sans-serif;color:rgb(31,73,125)">We have received a report of similar issues today. The client has servers with us in several locations where we use nLayer and/or PacketExchagne and his monitoring system is on a network that uses Cox as its preferred upstream. He shutdown his Cox upstream and didn’t have any issues reaching the servers over his backup provider. The issues were sporadic and did not affect all protocols – ICMP pings worked, snmpwalk was fine, but UDP traces were dying somewhere on the reverse path. Seems to be very similar to what you are seeing.<u></u><u></u></span></div>

We've been seeing intermittent TCP/UDP connectivity issues from Cox Communications in Virginia to any location that routes over nLayer. UDP traceroutes are fine, but DNS lookups time out for minutes at a time, then work again for ~5 minutes before repeating the problem. ICMP is never affected during the outages.<u></u><u></u></div>
