Request response times are between 20 and 40 seconds as opposed to 2 to 4 seconds on our office connection. Looking at my trace from LA, we are going LA<->Cox<->ARIN.

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.

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.
