I would be less worried if Cloudflare and AWS weren't involved in many more things than simply running DNS.

AWS - someone touches DynamoDB and it kills the DNS.

Cloudflare - someone touches functionality completely unrelated to DNS hosting and proxying and, naturally, it kills the DNS.

There is this critical infrastructure that just becomes one small part of a wider product offering, worked on by many hands, and this critical infrastructure gets taken down by what is essentially a side-effect.

It's a strong argument to move to providers that just do one thing and do it well.
