<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">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.
