Infrastructure

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

Contact

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

User:Ilario – infrastructure coordinator and operator
User:Valerio Bozzolan – infrastructure operator

Tasks

Every request can be reported on Wikimedia Phabricator:

phab:tag/wmch-infrastructure/

Access

Every server is accessible via SSH only through a Wikimedia CH VPN.

Once in the VPN, to enter in a server, we have to deploy your SSH keys in the right server.

Changes

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

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
