You can type! The accurate answer is that DNS updates are instant. Once those caches are expired, they are dropped and the next time your entry is resolved, you will see the correct result. Now, there are other factors that take part in this. For instance, DO batches updates to their name servers, so it may take a few minutes before they actually start responding with your latest zone. Also, your name server records on the TLD servers. Where would you like to share this to? Twitter Reddit Hacker News Facebook.

The lower the TTL is set the better - you usually won't get to "instantaneous" because of all the DNS servers out there which have diverse caching behaviours but the lower TTL is set the better your results will be Changes to DNS should be relatively instantaneous on your authoritative servers.

However, due to DNS cashing it will take a while for the changes to get out to clients. This will be more of a problem for frequent clients than occasional clients.

Any problems you encounter should be restricted to servers which are non-compliant with standards.

That's the issue - the email server will be the same. The building is switching to a new IP address pool and therefore only one of the IPs can be active at a time So I can't set up anything on the old one..

As long the the DNS admins are not setting unreasonably long times for their minimum TTL I support their actions to defeat these illegal operations. However, it does make transitions more difficult. When using our nameservers, your default MX record is your domain name which contains a local IP address to the server, so all mail is handled locally, but this record can be modified to point to a third-party email host, or you can add additional MX records and set their priority.
