Unlike DNSViz, Verisign's DNSSEC Debugger doesn't archive results, so here's a screenshot of my web browser's output from July 5, 2016:

July 4, 2016 opendnssec.org DNSSEC outage

OpenDNS & 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 opendnssec.org during this outage.

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

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

$ dig +dnssec www.opendnssec.org. @8.8.8.8
