Infrastructure

Welcome aboard, human! Bip.

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

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.

Contact

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

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

You may also want to file a task in the WMCH Infrastructure workboard on Wikimedia Phabricator.

Tasks

Every request can be reported on Wikimedia Phabricator:

• phab:tag/wmch-infrastructure/

Changes

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

• wmch-infrastructure on Gerrit

• 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)
