Hmm. I've asked the authoritative DNS team to explain what's happening here. I'll let HN know when I get an authoritative answer. It's been a few years since I looked at the code and a whole bunch of people keep changing it :-)
My suspicion is that this is to do with the fact that we want to keep affinity between the client IP and a backend server (which OP mentions in their blog). And the question is "do you break that affinity if the backend server goes down?" But I'll reply to my own comment when I know more.

- jgrahamc 2y agoThank you for appreciating my lame joke.
- mlhpdx 2y agoSo many sins have been committed in the name of session affinity.
- jgrahamc 2y agoLooks like this has nothing to do with session affinity. I was wrong. Apparently, this is a difference between our paid and free plans. Getting the details, and finding out why there's a difference, and will post.
- _cenw 2y agoWell, CEO said there is none, get on it engineering :)
- eastdakota 2y agoWhat’s somewhat complicated here is its apples and oranges. Cloudflare offers DNS and a proxy service. The OP is using both. The comparisons are merely DNS services. I wasn’t clear on X whether OP was getting confused that the IP we return via DNS (which points to our proxy) doesn’t change, or if they were concerned that behind the proxy we’re not routing correctly. I think after reading this the answer is the latter. Confident we always will route optimally as it’s in our interest and our customers’. But why we’re not failing over on failure is interesting. That looks like, as John said, a difference between free and paid plans that if it made sense at some point doesn’t obviously today. Will figure out what’s up and get fixed.
- dangoodmanUT 2y agoRegardless, it's really cool to watch you both engage with this
- jgrahamc 2y agoDon't forget all the people at Cloudflare who responded to a ping from me on a Saturday and looked into it. We are going to make the change. This will improve our free accounts so it's a win for everyone. Thanks to OP for writing this up!
- egberts1 2y agoPlease ignore the hidden master server, carry on.
- jgrahamc 2y agoUpdate: change is rolling out to do zero downtime failover on free accounts.
