RIPE Atlas is an Internet measurement network with over 10,000 probes located globally. It allows users to perform active measurements to monitor Internet infrastructure. Measurements are initiated through a web interface, API, or CLI and return real-time and historical data. The RIPE Atlas community includes users, hosts that contribute probes and anchors, as well as sponsors and ambassadors. Measurements use credits that can be earned through hosting probes, RIPE NCC membership, sponsorship, or vouchers.
