First the time it actually takes to get the two internet service providers “speaking” with each other to initiate and complete the move. We are speaking of about one full week!
Secondly, how smooth a move is actually going. Guess the important part to keep in mind is that there will be some time, where half the world’s DNS servers will still be referring back to the old host, whereas the other halfÂ already has the new host in there records. In case of cubetoon.com this wasn’t a big deal as there are no real transactions happening. If you are howeverÂ hosting a very database intensive site you may want to take this time lag into consideration.
