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

#square had an #outage. Now they tell their customers what it was.
(BTW 👍 for transparency and visibility, Square, even if comms could have been a touch more frequent)…
