The OWG has been holding fortnightly meetings with interested people working on specific operations-related topics. This allows people to help without the time committment of joining the OWG. If this interests you, you can contact us by email.
The OWG has switched all tile traffic to Fastly. If you proxy requests to tile.openstreetmap.org, you must ensure you set the Host header to “tile.openstreetmap.org and set a User-Agent to correctly identify who you are. We are considering what to do with the old cache servers, and if some of them can be repurposed. We will begin contacting people shortly.
The OWG is considering what to do with errol, the dev server. The current hardware is dated, and a lot of stuff running on it is unmaintained.
