WordPress MultSite down after changing IP address

We just moved our domain to a dedicated IP address yesterday on the same host/server. Now when you navigate to the page:


we get a default Apache/C-Panel page, and any subdomains carnaval.bz/london bring up the 404 message.

Wondering if there’s something in the configuration we overlooked? Taking a look at our database tables, there doesn’t seem to be any entry that points specifically to the old IP address. Thinking this may be a configuration issue on the server side (we have a support ticket open) but any advice is much appreciated.
