Moved from Amazon hosting, my domain is at GoDaddy and was using the following records for NS.

ns-255.awsdns-34.com
ns-551.awsdns-11.net
ns-1553.awsdns-24.org
ns-5525.awsdns-61.co.uk

I have since switched to the DigitalOcean DNS servers, waited 96 hours+ and reinstalled virtualmin

ns1.digitalocean.com
ns2.digitalocean.com
ns3.digitalocean.com

My domain name "example.com" no longer appears to be working, I get the directory listing but index.html does not display and no files show up, "host.example.com:10000" works so further confusing me..
