DNS propagation is the term commonly used to check the current state of results globally. This process can take only a few minutes or up to 48 hours or longer.
Technically the DNS does not propagate, but this is the term that people have become familiar with. Requests are forwarded from the locally used resolver to the authoritative nameserver on demand then cached to speed up future DNS lookups.
For popular websites, results may be cached for people in different parts of the world. If you have recently made changes to your configuration, this may mean that some people will be receiving old results until the TTL expires.
