For those with a more deterministic bent: "propagation" time has a maximum bound of your TTL, which will show with any dig queries.

- colmmacc 12y agoPropagation is bound at the DNS TTL plus whatever time it takes your DNS provider/setup to relay records to all of its authoritative servers.
- scott_karana 12y agoHmm, never considered that. Is it a slow, static process for ISPs to do that? I just assumed that they ran more-or-less stock DNS resolvers with in-memory caches.
