[AusNOG] Telstra DNS fallback to TCP? Anyone? or just me.

[Sean K. Finn]

Just curious as to see if anyone else is seeing any issues with Telstra Nameservers not resolving root glue and falling back onto TCP to lookup A Records for nameservers?

Getting varied reports from some customers who haven't added A records for their nameservers that anything resolving from Telstra, well, Isn't resolving.

Curious as to see if the Telstra Nameservers have temporarily suspended UDP traffic from the root nameservers due to major backscatter or some security appliance kicking in, hence falling back to TCP to do lookups manually.
