We know there is a lot of technical terms with web hosting and domains you probably prefer not to know. Propagation might not be one of those though. When you change a domain's DNS (domain name servers) or make any DNS changes. There is a time frame called propagation. This is a time when the change has been made locally, but the rest of the world has not updated their DNS to match it yet. Some smaller ISPs and even some smaller countries only update once a day. Most ISP services update within 4 hours or 14400 seconds. The larger ones update within 5 minutes. Back in 1998 when I started building websites it was 48 hours.
It simply takes more computing power for ISPs to update more often.
This is a good thing to know because new domains and DNS changes might seem like they are not working, when they really just have not propagated yet.
