Tech:Prod4

prod4 is a server in London running Ubuntu 14.04 (Trusty). Our Ansible playbook is available on GitHub. Ansible automatically pulls and runs the playbook on the server every 10 minutes.

nginx
nginx is the webserver. Its main tasks include SSL/TLS termination, gzip compression and FastCGI proxying. The nginx version is the Trusty version.

PHP
PHP5 worker processes are managed by HHVM.

SSL/TLS
The SSL/TLS configuration is extremely secure (SSL Labs test). It's inspired by the OpenSSL Cookbook.

MediaWiki
We run the latest version of MediaWiki and have a varying amount of extensions and skins installed to customise the experience for the end user.
