Will I have downtime switching to DNS Made Easy name servers?
Posted by Darren Radsmith on 26 October 2006 01:15 AM

You should never have any downtime when you switch to DNS Made Easy. The only time you have downtime when switching name servers is if your previous name server stops answering queries too soon. Even though you tell your registrar to assign the DNS Made Easy name servers to your domain some users will have queries answered by your old name servers for a few days. This is due to the cache of the NS records that can be stored on local networks. Technically it is due to the TTL of the glue records.

So it is crucial that the old name servers and the new name servers (new ones being DNS Made Easy) are both responding to the DNS traffic for the 48 to 72 hours "after" you notify your registrar. During this 72 hour period if both the DNS Made Easy name servers and your old name servers have exactly the same records in them for your domain, then everything will continue to work properly regardless of which servers are queried. After that 72 hour period it is safe to turn off the old name servers.

Most providers do continue to resolve DNS for your domains for a few days even though you are no longer using their name servers. But this is something that you will want to confirm with your provider to ensure a smooth transition.
