Items listed here are considered ultra-high-use and are often critical to the Wikipedia interface or used on many articles or other pages. Occasionally, individual templates will be part of a very closely-related family of templates, all of which should probably be cascade-protected to avoid problems; even if an individual template in such a family isn't widely used, it should still be protected for the same reason. Templates that are template protected or temporarily fully-protected (whether for vandalism, an edit war, or some other reason) do not belong here. Content pages (articles) should NEVER be added to this page.

This page is used to protect:

1. High-risk templates that should always be protected, using cascading protection. On occasion, accidental unprotection or transclusion of unprotected templates into protected templates have led to severe disruption.
2. High-risk files transcluded by them or used in the interface.

Do not delete or unprotect items because they are listed on this page! Don't do it, especially if a file has a backup copy on Commons. This page is meant to be an extra protection, to protect against silly mistakes, such as admins deleting or unprotecting high-risk templates and files. This cascade page is not meant to be the only protection. Items should generally only be removed from this page as a result of a deletion discussion closed as delete, in the course of complete deprecation in favor of a newer item, or because there is consensus to drop the item's protection to a lower level.

If this page causes any kind of problem, please ask on the talk page or speak to an(other) admin.

Changes must be requested on the talk page using {{editprotected}}.^[1] Cascading protection should not, generally, be applied to individual templates, since it protects their /doc subpages as well.

Often used in system messages and templates with Parser Functions.

The images listed here are protected even if they are accidentally deleted. Thus no-one can upload a bad image during that time. This also protects the images after they have been restored, since admins sometimes forget to re-protect the images after they have restored them.

Admins sometimes delete protected images by accident, or because they think we don't need them since they exist on Commons. But images are usually locally uploaded and protected here at the English Wikipedia since they are used in an interface message or in some widely used template. Thus these images are high-use and high-risk.
