Public DNS Queries

We've been running into some internet issues recently with a remote site that occurred around the same time we migrated to new Domain Controllers/DNS servers. For the remote site, access to various public websites will timeout or are very slow to load, while on other days these same sites work with no issues. I stopped by the remote site last week to check inside the network and so far everything looked good. Right now the issues seem to stem from our local office(the remote site connects to our site for access to the internet proxy and AD authentication). I've placed tickets with our Managed Services provider to check the internet equipment/configuration at the border or or network and the tickets come back with everything looking good from their end.

Anyone run into similar issues with migrating to DC/DNS servers with new IP Addresses?

Trying a nslookup pub.url 8.8.8.8 shows DNS request time outs at both the local and remote office.
