| What is domain propagation?
Propagation is the period of time, or delay,
involved in sending your domain's address information to all the
various name servers in the world. Name servers intentionally keep
track of addresses for domains in their memory for a specific period of
time (defined by the administrator of the name server). This speeds up
the process of looking up an address for a domain name. Unfortunately
this "cached" information also stays in the name servers when it has
been changed at the source of the original information (the domain's
registrar). Name servers refresh themselves from once an hour to once a
day. Experience dictates that 2-3 days is a good estimate for the
period of time from when a domain's DNS information is changed at the
domain registrar to when everyone in the world can see the change.
