Cloudflare Suffered Hours Long Outage (Which Brought Down Daring Fireball, Among Thousands of Other Sites)

Cloudflare suffered an hours-long global outage, starting around 12pm UTC / 7am ET, which brought down an enormous chunk of the Internet. This included, humorously, Down Detector. It also included (not so humorously to me) Daring Fireball, which has been routed through Cloudflare since 2018. My apologies if you tried to reach the site while it was down. (DF was back up by the time I woke up this morning.) As of this writing, Cloudflare still hasn’t determined exactly what happened, but they’ve been updating their status report for the incident a few times per hour. The most recent update:

We continue to monitor the system through recovery and we are seeing errors and latency return to normal levels. A full post-incident investigation and details about the incident will be made available asap.
