The Beta cluster is a functional, production-like environment in Wikimedia Labs suitable for final-stage testing of new features. It runs off git master and has its MediaWiki core and extensions code updated about every three minutes.


The aim is to provide an exact copy of the WMF production cluster (including db hosts, apaches, logging, squids, varnish caching, image scalers, etc.) using Wikimedia Labs instances.
