So what’s the one-word term for “cache expiry across multiple resolvers that handle caching differently, up to and including resolvers having more than one layer of cache due to forwarding”?

This isn’t a gotcha question: I know “propagation” isn’t a technically accurate word, but I’m sure not going to say that sentence when talking about it.

I would usually just say “after TTL expiry” to tech colleagues, but that doesn’t work for less technical conversations — saying “the change will take up to 24 hours to propagate” works better for explanations to C-level types.
