After talking with @leila , I think we're just going to self-host the site infra inside the WMF as a standard git-driven microsite like https://bienvenida.wikimedia.org/ and others. Details about content uploading and future management to be sorted out.
- Set up a git repo for wikiworkshop.org static content
- Set up basic microsite puppetization to deploy in our infra
- Configure SNI certificate for wikiworkshop.org on text cluster
- Switch DNS to our own hosting after content is ready (we already have the DNS, but are pointing it at a third party currently)
