Unlike DNSViz, Verisign's DNSSEC Debugger doesn't archive results, so here's a screenshot of my web browser's output from March 2, 2016:

March 2, 2016 .mm (Myanmar) TLD 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.

With OpenDNS, queries succeed:

$ dig www.google.com.mm. @resolver1.opendns.com.

; <<>> DiG 9.4.2-P2 <<>> www.google.com.mm. @resolver1.opendns.com.
;; global options: printcmd
;; Got answer:
;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 52962
;; flags: qr rd ra; QUERY: 1, ANSWER: 1, AUTHORITY: 0, ADDITIONAL: 0

;; QUESTION SECTION:
;www.google.com.mm. IN A

;; ANSWER SECTION:
www.google.com.mm. 300 IN A 216.58.216.227

;; WHEN: Wed Mar 2 05:58:40 2016
;; MSG SIZE rcvd: 51


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

$ dig +dnssec www.google.com.mm. @8.8.8.8

; <<>> DiG 9.4.2-P2 <<>> +dnssec www.google.com.mm. @8.8.8.8
