I am the sysadmin for community.openstreetmap.org and many other OSM services. This site is hosted on OSMF infrastructure, the setup / install is in managed via chef as per all the infra we host. The database and backups are managed by OSM operations team.
Yes, a HOT employee with discourse experience has been helping me with setting up the site over the last year. His employee has not been a factor I have worried about, it also hasn’t been hidden. He is 1 member of the @forums-governance team.
