Hot Take:

***Oh, Cloudflare, you had one job! Turns out, the internet’s knight in shining armor accidentally dropped its sword this time. While everyone was busy speculating about a grand cyberattack or a BGP hijack heist, it was actually just an internal facepalm moment. Who knew that a misconfiguration could cause such a global kerfuffle? Maybe someone needs to get the team a “DNS for Dummies” book for Christmas.***

Key Points:

– Cloudflare’s 1.1.1.1 Resolver service outage on July 14 was due to an internal misconfiguration, not a cyberattack.
– The misconfiguration was linked to a future Data Localization Suite (DLS) project.
– The outage affected global DNS services, but DNS-over-HTTPS traffic remained largely unaffected.
– Cloudflare plans to ditch legacy systems and improve internal documentation to prevent future mishaps.
– The incident was identified and resolved within approximately an hour.
