Judging by how many #itwasdns shirts I've sold this morning...

Is the Cloudflare outage DNS-related too? www.redshirtjeff.com/shop/p/it-wa...

I must be one of the lucky few that never need to say #Itwasdns

Somehow, for me, it's nearly never DNS

@jeffgeerling.com tried to warn us but we never listen. #itwasdns

Raise your hand if you ever inadvertently caused a 2+ hour outage (which was impossible to fix in a deterministic manner) due to DNS misconfiguration. #itwasdns

Completely sold out of 'Cosplaying as a Sysadmin' sticker packs on www.redshirtjeff.com, but still have a bunch of shirts left, like the classic 'It was DNS'! Going to restock soon, though. #itwasdns

Cool, cool. Looks like VirusTotal fucked up their DNSSEC settings. Or Google fucked it up for them. Other DNS services than the one I use allow resolving the CNAME and the resulting A record because they don't validate DNSSEC. #DNSSEC #ItWasDNS #VirusTotal
