Glad that we're speaking on the phone now! Our analysis indicates that ATT is having a a problem with at least Level3, Tata and HE at a peer point far out from our network. We have moved your route to Savvis and look forward to your call back after retesting. The affected ATT net block appears to thankfully be quite small and responsible for only 3-5 megabit worth of total outbound traffic from our network.
Wouldn't ya know it, the internet is a complicated place
