RIPE Altas

RIPE Atlas is a global network of probes that measure Internet connectivity and reachability, providing an unprecedented understanding of the state of the Internet in real time. There are thousands of active probes in the RIPE Atlas network, and it is continually growing. The RIPE NCC collects data from this network and provides Internet maps, data tools and visualisations based on the aggregated results. RIPE Atlas users who host a probe can also use the entire RIPE Atlas network to conduct customised measurements that provide valuable data about their own network.
