WordPress Multisite is available for Pantheon websites that are hosted on Performance plans.
Pantheon recommends at least a Performance Small plan for a small number of sites as that provides more power and memory, along with the use of Redis, as these enhancements are highly desired. For a multisite setup containing more than a few sites, a larger plan will be necessary.
If you are using domain-based multisites, you will need to have at least one Pantheon domain for each site in the multisite configuration. Should you exceed the domain limit for your current plan, contact [email protected] to increase the limit for your site without needing to upgrade to a larger plan. However, you will still need to upgrade to a larger plan if your site demands more RAM or workers than your current plan offers.
