The Deathwatch is meant to be a central indicator of websites and networks that are shutting down, or to serve as an indicator of what happened to particular sites that shut down quickly. New sites should be added in chronological order, newest death date first. Forward-looking death dates should be added to the first list only. Sites large enough to warrant additional information will receive a dedicated page, linked from here.
