I have been online for 30y and can't remember being affected by downtime from my ISP DNS.

When DNS resolver is down, it affects everything, 100% uptime is a fair expectation, hence redundancy. Looks like both 1.0.0.1 and 1.1.1.1 were down for more than 1h, pretty bad TBH, especially when you advise global usage.

RCA is not detailed and feels like a marketing stunt we are now getting every other week.

I too have been online for 30 years, and frequently had ISP caused dns issues, even when I wasn't using their resolvers... because of the dns interception fuckery they like to engage in. Before I started running my own resolver I saw downtime from my ISP's DNS resolver. This is across a few ISPs in that time. Anecdata is great isn't it?

I think we agree.

Your own "anecdata" shows how catastrophic DNS failures are and why it's justified to expect 100% uptime with proper redundancy. Too bad you had providers not architecturing properly this key part of their infrastructure to the point you had to build your own solution.
