Media Temple graciously sent me a personal e-mail in regards to the situation that I had late last week and helpfully explained the matter.

Originally I was concerned that they locked me out while they worked on the “ticket” and then forgot to let me back in, turns out my assumptions were wrong and the two issues were not associated with each other at all:

Regarding the Web Control issue, that was indeed an error on the (mt) side. We were updating/tightening our firewall config and inadvertently locked customers out of the Web control panel. This was a freak, one time occurrence and was corrected as soon as we realized the instance.
We apologize for the inconvenience caused by the Web control incident and assure you we are constantly striving to upgrade our customer service level along with our technologies.

Thanks (mt) for taking the time and following up, especially since it wasn’t a technician that contacted me through your help-desk but instead a personal contact through your Partner Director.
