OpenDNS vs. Google Public DNS

While Google Public DNS supports DNSSEC, OpenDNS supports the superior DNSCurve, which is (among other advantages) immune to DNSSEC failures. During this outage, Google failed to resolve names under opendnssec.org while OpenDNS worked normally.

With OpenDNS, queries succeed:

$ dig www.opendnssec.org. @resolver1.opendns.com

; <<>> DiG 9.4.2-P2 <<>> www.opendnssec.org. @resolver1.opendns.com
;; global options: printcmd
;; Got answer:
;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 48064
;; flags: qr rd ra; QUERY: 1, ANSWER: 1, AUTHORITY: 0, ADDITIONAL: 0

;; QUESTION SECTION:

With Google Public DNS, queries fail:
