Okay, maybe we're getting somewhere.

the two domains in question are served by the same two DNS servers:

;; AUTHORITY SECTION:
blackberry.net.         600     IN      NS      xns01ykf.rim.net.
blackberry.net.         600     IN      NS      xns01lhr.rim.net.

;; ADDITIONAL SECTION:
xns01lhr.rim.net.       159     IN      A       193.109.81.21
xns01ykf.rim.net.       160     IN      A       206.51.26.10

One of the RIM servers (xns01lhr.rim.net) appears to be down from here as well, so that could be what caused you to have a problem suddenly.

You probably want to look at the network path between your NS2 server and the xns01lhr.rim.net (206.51.26.10) server.

Going out on a limb here, but what's the netmask on your NS2 server?
