so cdn77.com and bunny.net

Yes, that's bunny.net, it's named in the post. Their Zurich PoP appears to sit on CDN77's network, which is on their side of the setup, not something we configured.

> There was no unauthorised access and no compromised systems. This was an overload attack, not an intrusion.

"AI said it's all good. There are no attackers within our walls."

Did AI write this?
nine_ch•36m ago
Yes. The blog version was drafted with AI assistance and then edited and reviewed by us. The facts, numbers and timeline are ours and match the technical postmortem PDF linked in the post, which is the drier, more complete version. Happy to go into any of the technical details here.
