Wait, are you saying that WMF uses MediaWiki-Vagrant to run the Wikipedias etc? I thought they was not correct.
No, MediaWiki-Vagrant is not used for Wikimedia's production hosting environment. It is however the only semi-official and semi-maintained (its a long story) shared development environment. I have worked for the Wikimedia Foundation for a bit over 5 years and have used MediaWiki-Vagrant as part of my development workflow for that entire time. We do not track statistics on MediaWiki-Vagrant usage among Foundation engineering teams, but I can anecdotally say that a number of teams either currently or in the recent past have used MediaWiki-Vagrant as their standard development environment as well. It has roles for setting up fairly exotic systems such as CentralAuth complete with a dedicated loginwiki or Flow with external storage.
MediaWiki-Vagrant uses a lot of custom Puppet code to provide a system that can reliably and repeatedly provision a wikifarm within a virtual machine (or LXC container) that comes about as close as one is reasonably able to running the same software with similar configuration to the actively maintained parts of the Wikimedia production environment.
