RIPE Atlas - Map Visualisations

DNS root instances Shows, for each Atlas probe, which root DNS server instance the probe ends up querying, when they ask a particular root server. In other words, it shows the "gravitational radius" for root DNS server instances.	Comparative DNS Root RTT Shows a comparison of response time for DNS SOA queries to all the root DNS servers. For each probe, a marker shows the "best" root server with color identifying the related minimum response time.	RTT to fixed destinations Shows the color coding for the RTT value for the particular destination for each Atlas probe. The minimum / average / maximum values are based on standard "ping" measurements.

Reachability of fixed destinations Shows if the particular fixed destination is reachable or not from each Atlas probe. Red markers indicate that the specific destination for these probes are unreachable and green reachable.	RIPE Atlas network extent Shows the extent of the RIPE Atlas network, with all active and inactive probes.	RIPE Atlas host volunteers Shows all hosts volunteering from around the world to run a RIPE Atlas probe.
