ウィキメディア財団のシステム管理者はウィキメディアのサーバのシステム管理の作業をします。主要な業務は財団の900以上のウィキが滞りなくうごき、利用者がページの閲覧や変更をしつづけられるように保つことです。ウィキメディアサーバークラスタのハードウェアとソフトウェアのメンテナンスのほか、ウィキメディアのサーバで走る MediaWiki のバージョンの更新と設定も務めます。ウィキの作成、ウィキの閉鎖、設定の変更など、サーバーやデータベースへの直接のアクセス権限が必要な管理業務も行うことができます。
The Wikimedia Foundation
legally controls the servers; ultimately the Wikimedia Foundation Board of Trustees
is responsible for determining who has sysadmin
access, and how that responsibility is exercised. However, this power is delegated to various Wikimedia Foundation managers
. On a day-to-day basis, various system administrators with root or shell access manage the server clusters.
Although system administrators are often not active on Wikimedia wikis themselves, they may occasionally need to perform actions for technical reasons, such as blocking users or bots that are consuming unacceptable amounts of system resources, or undoing edits that put heavy strain on the servers. Such actions should not be undone without consulting the system administrator.
To facilitate these changes being made in a transparent fashion with no need of the steward flag, all system administrators who ask can be added to the 'sysadmin' global group
(automatic members lists
). This group allows them to set user rights for any user on any wiki, in the same fashion as stewards
. So if a system administrator needs to perform an action restricted to administrators (like editing system messages) on a particular wiki, they can simply grant themselves admin status on that wiki to make the action. In addition, the 'sysadmin'
group has access to Special:GlobalGroupPermissions
, where system administrators can change
the permissions assigned to their global group. So as an alternative, the system administrator could add editinterface
to the global group permissions, and would then be able to edit system messages on all wikis.
System administrators are encouraged to use the latter method of granting permissions, to avoid the lists of administrators/bureaucrats on local wikis becoming cluttered with users who are not 'permanent' members of those groups. These self-promotions may be removed at any time by stewards, as they can be easily restored if needed. However, some system administrators have permissions on certain wikis as a result of due process on that wiki, for instance Tim Starling's
adminship on English Wikipedia
; such rights should not
be removed in this fashion.
The list below is provided for convenience and should not be treated as accurate or complete. Most of the technical Wikimedia Foundation staff
have some form of shell access. There are various levels of shell access (through user groups) and many (whether or not overlapping) groups of servers that access is granted to. For simplification the list below considers all servers to be the same and there to be only (regular) "restricted", "deployment", and "ops". Some other users (not necessarily listed here) have the ability to perform highly restricted actions in some miscellaneous services, with varying degrees of visibility to users.
Initially, it was Jimmy Wales who installed software, ran update programs, etc., on the servers. In March 2002, he proposed to give login accounts to some developers ("Trusted user access to machine
System administrators formerly had an important role in the Wikipedia power structure
, since they were the only ones able to promote and demote sysops and lock user accounts (before the "block" feature of MediaWiki
Some sysadmins had shell access to the old California servers, but due to inactivity, weren't given shell access on the "new" (since decommissioned) Florida servers. Magnus Manske, April King, Lee Daniel Crocker, Axel Boldt, Matthias Jordan, Neil Harris and Ed Poor were all in this category.
