The support you get depends on where you get your license. I got mine straight from Interworx because I figured they'd know more than anyone of course. I've only put in a few requests and they were good experiences. The support direct from Interworx is only normal business hours though. I'm sure that some resellers provide 24/7 support. Most of the time I don't even need to submit a ticket though because if I submit a thread in their forum I always get a quick reply. As for support capabilities, the panel has an integrated remote support API feature just like cpanel does so if you want them to they can login and help you fix whatever problem there is. Support is included with the license.
