"We found three concrete gaps during this incident, and we would rather be upfront about them than gloss over them." claudism?

Sticks out like a sore thumb, doesn't it?

> 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."

I sometimes work on a system so byzantine and poorly-documented with so many horribly obsolete systems - they have Windows XP machines all over the place - that there's no way it hasn't been popped.

I think it's safe though.

I think various groups have popped it, taken a look around with growing expressions of horror on their faces, and gotten back out as quickly as they could. Nah man, no way, not touching that, don't want my prints on this particular gun, there's no way this is legitimately how they've left it, this has to be some kind of a setup.

Did AI write this?

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.

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.
