The most likely reason
for this problem is that the DNS at your ISP is not updated to reflect
the changes in Internic (or other NIC) database.
It normally takes 2-4 days to propagate the new DNS information
and clear DNS cache. This time depends on the TTL (time-to-live)
settings for your domain at your previous host and the time when
DNS entry was cached.
Sometimes, it takes more than 4 days if the TTL was set unreasonably
high by your previous host. In some cases it may take as long
as 7 or 10 days to clear the cache.
During this period the mail and HTTP requests may be coming to
either the old or new servers. There is no control over it and
nothing can be done to speed up the process.
You can verify this by using ping or trace route utilities. If
you are using Windows 95, 98, or NT you need to type at command
prompt either of the two commands:
- ping your_domain.name
- tracert your_domain.name
The reported IP address should be the one of your virtual server
with UCVHost. If this is not the case and it has been more than
7 days since the domain record had been updated, please contact
your ISP to solve the problem.
