What's the actual issue? Are you being frustrated by people laboring under the assumption that DNS records are being sent by carrier pidgeon or something?

DNS censorship will presumably be based on geopolitical boundaries, which in turn are bound by geography. And I wouldn't be entirely suprised if poor network connections - including those potentially geographically bound (poor weather / flooding / tornados severing or degrading links or power) had some (minor, infrequent) impact on the rate stale cache entries are evicted in favor of fresh ones.

Granted, none of that means a DNS resolver halfway across the globe from the authoritative servers can't typically get updated results <200ms (≈light speed), which is safely ignorable / won't be visible as records propagating from geographic neighbor to geographic neighbor. And granted further, I'm both too boring to censor, and too smart to be on call for anything that would make me aware of global outage reports - so the map is admittedly useless to me beyond farming that hacker vibe aura.

But I imagine there's at least one or two dudes out there that'll see a red dot in, say, Australia - and that'll save them a few minutes, by giving them a shortcut to determining the root cause of some issue reported in Australia by letting them correctly guess/blame stale DNS records.

The actual issue is that some people misunderstand how DNS works, and the notion that records propagate doesn't help people understand it better. It propagates a misunderstanding of DNS.
