The Quantum hosting plan is a revolutionary new addition to our Managed WordPress hosting lineup, available exclusively to our Agency members.

Select Quantum plan when creating a new site

While Quantum is not suitable for e-commerce sites, it is ideal for small blogs, static sites or when developing new client sites. Sites can be upgraded to any other plan at any time.

Quantum offers the same fully dedicated architecture as our other hosting plans, at the lowest price possible.

To achieve this, we’ve had to pare down some of the features available on this plan to avoid maxing out server resources and ensure your site has the power it needs for optimal performance.

This document aims to inform you of those restrictions so you don’t hit any unexpected snags.

Please see our Plans & Usage Limits doc for more information on server specifications for this plan.

What happens if I downgrade my WPMU DEV membership?

Any Quantum sites that you have created while on the Agency membership will continue to function normally if you downgrade your membership, and you’ll be billed for them as usual. You just won’t be able to create any new Quantum sites while on the other membership plan.
