I'm was right in the middle of doing some "tidying up" and ...oops... gone. Oh well, it'll be back soon enough....
My advice, being that they're patching a security issue, and updating the cPanel/apache on the free servers, I'd expect a few more small "bumps", but all is looking good. Be patient.
As far as support tickets... I'd HIGHLY recommend waiting AT LEAST 24 hours before submitting UNLESS otherwise instructed. Support has been SEVERELY overloaded with support tickets, that in most cases have RESOLVED THEMSELVES. So unless you find something in the forums stating to submit a ticket for YOUR current problem, please wait a minimum of 24 hours before submitting a ticket.
Our admins are aware of this, and have already posted that there will be some intermittent outages while our cPanel is updated and Apache is recompiled.
