Post-mortem

Hah! There isn't one, and Namecheap didn't even mention this outage on their status.namecheap.com website. It was only discussed on Twitter by angry customers.

Hacker News

This DNSSEC outage was briefly discussed in the Hacker News thread Namecheap Has DNSSEC Outage, No Disclosure on Status Page, Refuses Post-Mortem.

DNSViz / Zonemaster

DNSViz was (and still is, at the time of this writing) having a non-DNSSEC related outage. A notice on the site states "DNSViz will be without the historical functions of the tool for a little over a week while its hardware is in transit between Verisign and DNS-OARC. The historical functions will be brought back online during the week of February 11th." So the historical functions should have returned a week ago. I contend that DNSSEC makes its proponents numb to outages, and that this lack of seriousness creeps into other aspects of their tech stacks.

That said, the Twitter users @zmarty and @Foritus noted above have the domains ovidiudan.com and aornis.com, respectively, in their Twitter bios. Whois currently shows both domains registered through Namecheap. And at the time of this writing, DNSViz shows ovidiudan.com to have disabled DNSSEC by removing the DS record (keeping the RRSIGs). So apparently @zmarty disabled DNSSEC to maintain DNS availability.

Since DNSViz is essentially having a multi-week outage, here's a 3rd party citation of the above claim courtesy of zonemaster.iis.se. It shows RRSIGs but no DS record.

Additionally, zonemaster.labs.nic.cz shows a missing DS record.

Please note that missing DS records don't cause outages — they fix them! I'm only showing that one of the people claiming an outage appears to have disabled their own DNSSEC, which supports their claim of a DNSSEC outage.
