	<p>The Tor Metrics team plans to shut down the Compass service at the

	end of December 2017.  Aggregated search functionality has been

        integrated into <a href="https://atlas.torproject.org/#aggregate">Relay

	Search</a> (formerly known as Atlas) to give a unified tool for

	exploring both single relays and aggregations of relays.<p>

        <p>Please ensure that all the functionality you require is available

	in Relay Search before Compass is shut down. If any functionality is

        missing, please <a

	href="https://trac.torproject.org/projects/tor/newticket?component=Metrics/Atlas&parent=%2324445">file

        a ticket to request that it be added</a>.</p>
