Sorry if I'm missing something here but what does DNS have to do with this?

If you used ping www.name.here it's obvious that a DNS lookup has been
successfully performed since you're getting the IP address and the DNS
lookup goes before any packets are sent. If you used ping then
DNS was not involved since, as set up normally, ping does not do any reverse

If you are experiencing problems with Traceroute then look at the numbers -
not at the real world time it takes for the name or number to appear.
Traceroute uses DNS initially to get the IP address and then only performs a
reverse lookup AFTER it has received that hop's IP address.

What would appear to be at fault is a link or routing somewhere along the
line between you and this server.

Check with you ISP to see if they see similar.
