Just I was not then (a little better now) very good at understanding what it was all about dropped on Hostway by luck based as far as am aware in docklands also, when their closed calls/emails seem to be routed the states so you still get rapid replies. Also in the begining they were patient answering my questions.

In reply to a post by RobertoS:

The DNS servers - there are hundreds/thousands around the world and it takes a while for all to get updated. None of them will look at both places, just some will look at (point to) the new address after a few hours and some could take 24 hours or even a bit longer to do so, so they continue to point to the old until then.

You can manage this if you have a DNS host that lets you edit your entries (zone) directly. You then reduce your Time To Live (TTL) values on your entries to 20mins, then when you move to a new host, the other DNS servers around the world should expire their cache within TTL * 2. Some ignore TTL, but the majority (over 98%) will be affected.

Then when you're safely on the new size, you increase the TTL again.

Yes, I (sort of) knew that. However that is a workaround for the subject/problem, where the way it worked needed to be explained. Which is what I did.

I never bothered tweaking the TTL on my moves as I didn't see the point. If the old site had been about to disappear then of course that's different.
