Unlike DNSViz, Verisign's DNSSEC Debugger doesn't archive results, so here's a screenshot of my web browser's output from June 27, 2016:

June 26, 2016 yadifa.eu 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 .mm during this outage.

$ dig yadifa.eu. @resolver1.opendns.com.

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