I have an amazon AWS server running Ubuntu. It currently holds 4 websites, and I changed the DNS for these sites at 08:00 this morning.

It is now 15:30 in the afternoon, I set the TTL down to 60 however :

3 of the 4 sites have propagated.

1 of the 4 sites is still responding to the old IP address still.

Am I missing something?

First, use nslookup to query your name servers (listed in the Route53 management console when you select your zone) directly.
You do it like this:

nslookup my.query.com ns-????.awsdns-??.???

If this query doesn't give you the right results, the issue is between the AWS console and Amazon's servers, so you should contact them.
If this looks OK (like I think it would), then you have a problem of propagation - some DNS server in your hierarchy (your PC asks server A, which asks server B, which asks... ending in Amazon's nameserver) is misbehaving, and not Amazon.

  • The strange thing is that The server holds 3-4 domains and all but 1 have resolved :/ – JustSteveKing Dec 17 '14 at 15:14
  • @JustSteveKing, the name servers for the domains don't have to be the same - are you sure you're querying the right ones? – Nitz Dec 17 '14 at 18:19
