Which Powerhouse Sites Got Hit Hardest?Cloudflare's role in shielding websites from cyber threats and optimizing speeds made its downtime a domino effect. Here's a quick rundown of the casualties:
Even Downdetector – the go-to outage tracker – flickered offline, amplifying the confusion.Unpacking the Culprit: A Traffic Spike Gone WildNo hackers or cyber villains were to blame here. Instead, the outage stemmed from an internal gremlin: an auto-generated config file for threat filtering that ballooned way beyond normal limits. This oversized file crashed the core software handling traffic for Cloudflare's vast network.Experts point to this as a classic case of "scale failure" – when protective measures ironically become the weak link.
