This will be distributed automatically to nodes, which will evaluate the fact when they make a catalog request, providing the result among all the other fact values. These will then be recorded in PuppetDB <https://puppet.com/docs/puppetdb/5.1/api/query/v4/facts.html>, from which you can query the results, and the values will be available during catalog building as top-scope variables.
