On November 2, 2023, Cloudflare's customer-facing interfaces, including
their website and APIs, along with logging and analytics, ceased
functioning properly. That was bad.

Over 7.5 million websites use Cloudflare, and 3,280 of the world's
10,000 most popular websites depend on its content delivery network
(CDN) services. The good news is that the CDN didn't go down. The bad
news is that Cloudflare Dashboard and its related application
programming interfaces (API) were down for almost two days.

That kind of thing just doesn't happen -- or it shouldn't, anyway -- to
major internet service companies. So, the multi-million-dollar question
is: 'What happened?' The answer, according to Cloudflare CEO, Matthew
Prince, was a power-related incident at a trio of the company's primary
data centers in Oregon, which are managed by Flexential, that cascaded
into one problem after another. Thirty-six hours later, Cloudflare was
finally back to normal.


(as others have pointed out and CF has more or less acknowledged: three
data centers in one small city can be expected to share their fates in
many scenarios.)
