Re: DNS settings
if you use nslookup what does the record for your site return?
at the command line.
then type your domain name
you'll see a value marked TTL that's time to live. it tells DNS servers how long they should cache the result for.
this can be set for a long time by some name service providers, as it tells other servers to cache addresses so that they receive less traffic,
on the other hand t leads to a greater state of flux when you;re changing hosts.
imagine that the TTL is 1 hour.
at 11:55 computer 1 looks up the site and gets address A
at 12:00 you move the site. (and change the record)
at 12:05 computer 2 looks up the site and gets address b (the new site)
but computer A is still going to use the cached data and look for address A until the record expires.
so even at 12:54 computer A will still try to get to your old site.
Now imagine that TTL is a day, (or more!). and see how long it's going to take to clear up that DNS cache.
you can use ipconfig /flushdns to flush out all records on your local PC.
but that's not going to help if your home router is your DNS server because that will have cached the record, and if that get it's DNS information from your service provider, then your service provider will have cached the old data too!
