Propagation is the wait while DNS servers around the world pick up a record change.
You change the A record and see the new site at once. Your customer across town still sees the old one for a while. Their DNS resolver holds the cached answer until its TTL runs out.
It usually takes minutes to a few hours. It can take up to two days if the old TTL was long. Nothing is broken. It is just waiting.
We keep your old site up during propagation, so visitors see one or the other, never an error page.
TTL, or time to live, is how long DNS answers may be cached before being looked up again.
DNS is the phone book that turns your domain name into the address of the server that holds your site.
An A record points your domain name to the numeric address of a server.
A CNAME record says one name is an alias for another name.
Paste your URL. We rebuild it, show you the match, and measure the speed. No template. No blank page. Human review from start to finish.
