There are a lot of questions and answers about Media Temple WordPress hosting from its knowledge base, but those may not meet your demands. Here is a list of frequently asked questions and answers I collected during my testing of its Managed WordPress hosting, it may helped to you.
How Many Visitors Could Media Temple WordPress Hosting Handle
From the beta version to officially released version, there is no precise bandwidth or CPU resources limits set to Media Temple WordPress hosting solutions. I contacted the support team and got an answer to that question:
There are no individual resource or RAM limits for sites. The WordPress Hosting service is a shared service, so your sites share the resources of a network of servers with other customers. We personally will take no action (if you exceeded the 400,000 visitors limit of your Personal package in a month), but it is likely that you may encounter performance issues on the site.
In other words, for now, before Media Temple update their WordPress hosting packages limits, your sites can handle as many visitors as you can. If you have a WordPress site which have more than 1,000,000 visitors per month, Personal package is also suitable.Don’t worry about the limits, start produce more high quality contents for your visitors, as a managed service, Media Temple will solve all problems for you.
