how are you going to find out if they are mostly in private company networks? sounds hard unless you would start a mail campaign to ask them?

@Dzhan, the information is indeed hard to find. An email campaign was something that we thought about a month or two ago and may be useful and deserving of another look. Thanks for the ideas and comments - they are most welcomed. :)

In the meantime, we also decided on T1113: Link to survey on 1.24 installer and T1136: Extract and Sort WikiApiary Database .

fwiw, there is also a bug that suggests adding some kind of opt-in "call home" feature to the wiki installer, so people who install mediawikis could allow it to report to us automatically that one is being installed. this is completely just an enhancement request though, nothing of it actually exists

this is the bug: https://bugzilla.wikimedia.org/show_bug.cgi?id=54425
