Infrastructure

Wikimedia CH has a small but efficient server fleet. Here some public information.

Contact

If you have any question feel free to contact one of the users with access in the network:

• User:Ilario - has a lot of experience on the tech projects hosted in WMCH (staff member)
• User:Valerio Bozzolan – infrastructure operator (WMCH Tech Boosts)

Tasks

Every request can be reported on Wikimedia Phabricator:

• phab:tag/wmch-infrastructure/

Access

Every WMCH server cannot be accessed via SSH without being in the WMCH VPN:

• Infrastructure/VPN - Wikimedia CH VPN

After you have obtained your WMCH VPN credentials, stay ready to share your SSH public keys, to deploy them on the desired server, to be then able to access.

Changes

Every important configuration change is tracked inside our repository to identify regressions:

• wmch-infrastructure on Gerrit

Legacy infrastructure

Server intern

There is a legacy server called intern and exposed via https://intern.wikimedia.ch/ that hosts some legacy MySQL databases.

Here some hypothesis about the purpose of each database:

• b00028.board_ – legacy running wiki about https://board.wikimedia.ch/
• db00028.chapters_ – legacy running wiki about https://chapters.wikimedia.ch/
• db00028.members_ – legacy unused database previously related to https://members.wikimedia.ch/ (phab:T255848)
• dbwiki_chapters – legacy wiki about https://chapters.wikimedia.ch/ (note: no users, just contents)
• dbwiki_executive – legacy unused database previously related to https://executive.wikimedia.ch/ (note: no users, just contents)
• dbwiki_members – legacy unused database probably an old backup of db00028.members_ (note: no users, just contents)
• dbwiki_test – unknown
• dbwikimania – unknown
• dbwikivillage – unknown WordPress
• dbwlm – unknown WordPress
• dbwwwprod – unknown CiviCRM + WordPress
