When sites deactivite, dns caches them offline

[xmuskrat]

If I have a site that auto-deactivates, say, it expires and somebody visits the site the website stays down even after I reactivate the site. This happens for everybody that uses the same ISP. It appears that the DNS server (in this case Comcast) caches the site is down and does not retry until their cached records expire.

Why did Parallels change the previous behavior of turning off the DNS server for the domain instead of serving a "default page"?

It means that whenever a client gets automatically shut off, and they call me, I have to tell them the site won't be up for a few hours. This is really bad.
