 | This page is a policy on the Simple English Wikipedia. Many people agree with it. They see it as a standard idea that all users should normally follow.

 | This page in a nutshell: A steward may block an IP address from changing pages on all WMF projects to prevent it from causing cross-wiki disruption or to enforce the policy against editing from open proxies. |
GlobalBlocking is a MediaWiki extension available to stewards to prevent cross-wiki disruption from an IP address or a range of IP addresses. When an IP address or range of IP addresses is globally blocked, they are stopped from editing any public Wikimedia wiki, except for Meta-Wiki, where globally blocked users may appeal the decision.
A current list of globally blocked users is available at Special:GlobalBlockList.
Unblocking and appeal
Local whitelisting — A user who is globally blocked can be unblocked locally (to edit the specific wiki concerned only), by any administrator, at Special:GlobalBlockWhitelist.
Appeal against a global block — users who are globally blocked may appeal the block at Steward requests/Global, on Meta-wiki.
