DNS propagation Checked from US1, Miami, Florida
Queries 7 public recursive resolvers and the
domain’s own authoritative nameservers. The resolvers show what the internet currently sees; the
nameservers show what has actually been published. When those two disagree, the change is still
propagating. Checking from all three locations compares Dhaka against Miami, since public resolvers are
anycast and otherwise answer from whichever node you are on.
