If restarting the entire VPS when the Apache configuration wasn't changed didn't fix the issue, that would suggest that it has nothing to do with Apache or its configuration, but that inbound port access is being blocked outside of the VPS.
>From a different box than the VPS, preferably not on the same network as the >VPS is running, run: traceroute test.example.com -p 8880 Using the actual external hostname or IP of the VPS and the port Apache is meant to be listening on. Also do that from the VPS itself. Report the results. Only other things I can think of is that are using an IP address in the VirtualHost definition rather than a '*' and the IP address by which the VPS is being contacted is changing. Do not hardwire VirtualHost to a specific IP unless you have a specific requirement.
