General
- Cloudflare Outage, lasting just under 6-hours end-to-end
A Cloudflare spokesperson said the “root cause” of the outage was an automatically generated configuration file used to manage threat traffic that “grew beyond an expected size of entries,” which triggered a crash in the software system that handles traffic for several of its services.
“In short, a latent bug in a service underpinning our bot mitigation capability started to crash after a routine configuration change we made. That cascaded into a broad degradation to our network and other services. This was not an attack”
