When it comes to servers I defiantly struggle I have recently set up a rack space cloud. I have two domains pointing to it: and the actual domain I will be using for it

For some reason takes around 15 seconds to resolve, where as takes no time what so ever.

I'm running ubuntu 10.10 maveric.

What could possibly be causing this?

What is doing the resolving? Are you using the rackspace nameservers? – blankabout Apr 15 '11 at 22:46
Please give details on how you are testing the resolve. Both names resolve quickly for me using Google name-servers or AT&T name-servers. – BillN Apr 15 '11 at 23:45
Is this an ad for those two sites? – Mark Wagner Apr 16 '11 at 1:16
As an aside, be prepared to lose that first domain as part of a UDRP complaint. That is a pretty blatant trademark violation. – Justin Scott Apr 17 '11 at 4:56
@blankabout I am using the rackspace nameservers I only set the first site to be apart of the rackspace account since I'd never done it before and wernt going to blindly stop pointing my domain to a new server without knowing I could get it working or not, its not an advert either @embobo. Im not server savy so Im seeking advice from experts who clearly know/have a far better understanding then myself, and Iv owned the first domain for years, it was used just for TEST purposes, I was just going by the basis that it seems to take while to load, but there may be other iimplications there – blakey87 Apr 22 '11 at 10:13

When I did a dig, this is what I got. How are you measuring the DNS resolution time. The time taken to connect to is not the correct way of measuring DNS response time.

$ dig

; <<>> DiG 9.7.1-P2 <<>>
;; global options: +cmd
;; Got answer:
;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 57080

;       IN  A

Even with a +trace flag, dig it takes 306ms
