I understand there are API limitations, but isn't 15 minutes a lot for an object that orbits around the entire Earth in 90 minutes? On average you're going to be off by about a twelfth of the circumference of the Earth, or roughly the distance between Lisbon and Istanbul

Yes. As I say in the post, you shouldn't use this for docking operations.

If you know of a DNS update which allows for per-minute updates for free, I'll happily move to it.

Remember people, DNS stands for "Definitely Not for Space-docking"

It’s quite easy to run your own DNS server — I've found it a worthwhile exercise. Of course, you’ll need a server to run it on.

Does Cloudflare not allow this?

Cloudflare does this with an API. If you have any money, I'd suggest dnsimple.com instead.

At orbital speed of ~7.66 km/s, the ISS travels approximately 6,900 km during a 15-minute interval, which is indeed significant for precise location tracking.
