: How to make DNS server propagate faster if you are a site owner? It's often the case that I want to change name servers because my site is messed up. Well, it takes a very long time for

I recently ran into a similar issue, I couldn't update the live site until my ISP flushed their DNS cache (which was well over the 2hr TTL I had set). What worked for me was using Google's Public DNS developers.google.com/speed/public-dns/ It might not cause faster worldwide propagation, but it can allow you earlier access if your ISP is slow to update.

The "time to live" (TTL) on DNS records controls how long it takes for DNS changes to propagate. It is fairly common to set TTL to a low value like 30 or 60 minutes to be able to switch a web service over to a hot spare in case of downtime.

Here is an article about TTL that you may find helpful.

This does require the advanced planning of having already set a shorter TTL well before you have the need to fail over. If you need to fail over right now, you are out of luck. DNS will take as much time as your previous TTL setting.
