So, my company hosts hundreds of wordpress sites. We turned off auto updating of wordpress core files because we have modified core code for better SEO / better security. Every so often we grab the next version and move our changes over, test it and then push it out to all of our sites manually.
I would like to create a server that helps with pushing our new / updated core code to all the wordpress sites through the auto update.
Essentially I am looking for our wordpress intances to auto-update from a server on OUR side instead of from wordpress servers.
If you’re using something like GIT for version control, you can set up your altered wordpress core files in it’s own repo and then include them in your deployments as a submodule.
An example would be this repo where they have set up WordPress as a submodule.

Instead of using the official WordPress repo as the submodule, you would use your altered one.
