Thanks.

Yesterday I got the same problem. When I try to reboot my VPS (just test), the IP became un-pingable after I click the reboot button. I went to dedicatedchat and sysadmin solved the problem very quickly.
I then asked the reason, because I recall I did try to reboot my VPS last weekend before the first downtime. The answer is the IP 74.50.2.98 is not properly reassigned to my VPS after the reboot. So if this problem happens next time, I won't be able to use Virtuozzo panel because the IP will still be unaccessible.
You are right. Once I migrate some of my sensitive clients to here, I will consider the managed addon later. I am not a picky person, but someone do.

The IP unaccessible really hurt a bit for the private DNS sit on it and do Mail server. Most people don't care about web but emails.
Anyway, thanks for the help and useful comments, really appreciate.
