OpenDNS and Google Public DNS

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

With OpenDNS, queries succeed:

$ dig www.usfj.mil. @resolver1.opendns.com.

; <<>> DiG 9.4.2-P2 <<>> www.usfj.mil. @resolver1.opendns.com.
;; global options: printcmd

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