Domains work for some, not others.

Recently I purchased a VPS server and Im having some trouble setting up domains and DNS etc. I'll start off by linking to this Network-Tools.com test:
http://network-tools.com/default.asp?prog=express&host=dunder-mifflin.org

The hostname for my server is SERVER.DUNDER-MIFFLIN.ORG.

So far, what I've done is created hostnames at my registrar (NS1, NS2, and SERVER). In DA, I've assigned NS1/NS2.DUNDER-MIFFLIN.ORG to two of my three IP addresses. The third IP is the server IP.

There are a few problems. Firstly, some people can get to the domains hosted on the server, while others can't. Either you can resolve all of them, or none.

When I ping NS1, I get an OpenDNS IP (I use OpenDNS at home, not on my server). The IP is 208.67.217.132. It should resolve to 204.27.60.89, because that's the IP I've assigned NS1 to in DA. When I ping NS2, I get 204.27.60.89, which is an IP that I own, but it is not the IP I've assigned to NS2. It should be 204.27.60.90.

Does anyone have any idea what's going on here? Thanks for the help!

EDIT: Since posting this, I've switched the NS1 and NS2 IP addresses at my registrar as well as in DA. Looks like the changes have gone through, because when I ping NS1 and NS2 now, they resolve to the correct IPs. However, other people can't see this yet... it could be because it hasn't propagated yet. Anyone else have any ideas?

Using dig +trace +additional I see this:
Code:

Seems fine to me, it probably hasn't propagated everywhere yet. The ".org" TLD nameservers use 86400 (24H) as TTL for the NS records, so you'll have to wait a whole day to be sure.
