One of the biggest challenges with DNS changes are the propagation from the "master" DNS servers down to their virtual/children DNS servers. In Canada, Bell Sympatico is extremely slow to update all of its virtual DNS servers, so I have had to switch over to use the Bell Nexia DNS servers. It is not uncommon for it to take up to 3 weeks for a DNS change to take hold.
