“Recent Checks OK” = how many of our last test calls (up to 20) worked: the service asked for payment correctly. Shown once there are at least 5 recent checks and at least one worked. “Needs Login” means the service asked for a key or login (HTTP 401 or 403), which is not a failure. These are facts, not a quality ranking. Services can reply or dispute.
