OpenDNS & Google Public DNS

OpenDNS does not support DNSSEC, and instead supports DNSCurve. Google Public DNS currently supports only DNSSEC, and thus, Google's users saw SERVFAIL for queries under marines.mil during this outage.

With OpenDNS, without DNSSEC, queries succeed:

With Google Public DNS, because of DNSSEC, queries fail:

$ dig +dnssec www.marines.mil @8.8.8.8

drill trace

Since DNSSEC contains so much garbage, I put the complete drill trace into its own file, with the relevant portion below (emphasis added):

;; Domain: marines.mil.
