NRB rates stream reliability as follows:
- Stream is rock-steady on our technology, seldom dropping out, skipping, rebuffering, or garbling.
NRB stream reliability rating: Excellent
- Stream is usually stable, but drops out occasionally or has minor or intermittent signal quality issues.
NRB stream reliability rating: Good
- Stream has significant sound quality issues or is susceptible to rebuffering or drop-out; scan-capable software frequently skips to other stations when streaming this station. Stream may go entirely dead or uncopyable, but a message to the station typically restores it to former reliability or better.
NRB stream reliability rating: Fair
- Stream is highly unreliable, susceptible to drop at any minute, or outright disappear for long periods. Station doesn't answer or act on listener feedback; it may publish no contact information.
NRB stream reliability rating: Poor
