Re: Changing ISP''s

We just moved and reconfigured a bunch of things...

One thing to note is that some DNS servers will cache OLD dns up to the
EXPIRATION time. I though the expiration time was the length of time a
secondary could keep data, but it appears that some DNS servers cache
until that time expires... shouldn't they use the MINIMUM time?

Just checking...

Anyway, after our 3 day expiration time went out, AOL shifted the MX
records that it was caching... other records seemed to have expired fine,
so perhaps it wasn't the DNS servers doing the caching, but the Mail
Servers?
