A colleague of mine just came bursting through my office door in a panic, thinking he brought our site down since this happened just as he made some changes to our Cloudflare config. He was pretty relieved to see this post.

Well, you can never be sure that he didn't: https://www.fastly.com/blog/summary-of-june-8-outage

I'm pretty sure I crashed Gmail using something weird in its filters. It was a few years ago. Every time I did something specific (I don't remember what), it would freeze and then display a 502 error for a while.

It's also what was the cause of the Azure Front Doors global outage two weeks ago - https://aka.ms/air/YKYN-BWZ

"A specific sequence of customer configuration changes, performed across two different control plane build versions, resulted in incompatible customer configuration metadata being generated. These customer configuration changes themselves were valid and non-malicious – however they produced metadata that, when deployed to edge site servers, exposed a latent bug in the data plane. This incompatibility triggered a crash during asynchronous processing within the data plane service. This defect escaped detection due to a gap in our pre-production validation, since not all features are validated across different control plane build versions."

How did we get to a place where either Cloudflare or AWS having an outage means a large part of the web going down? This centralization is very worrying.

This topic is raised every time there is an outage with cloudflare and the truth of the matter is, they offer an incredible service, there is not a bit enough competition to deal with it. By definition their services are so good BECAUSE their adoption rate is so high.

It's very frustrating of course, and it's the nature of the beast.
