OpenDNS and Google Public DNS
OpenDNS does not support DNSSEC, instead supporting DNSCurve. Among other advantages, DNSCurve is immune to DNSSEC outages. 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:
$ drill -D www.usfj.mil. @resolver1.opendns.com.
