Volunteers from across the world help RIPE Atlas reach new places every day by hosting probes, the building blocks of our measurement network. Probes perform the active measurements RIPE Atlas uses to collect data on Internet connectivity and reachability. Hosting a RIPE Atlas probe is easy. You can either apply to host a hardware probe, which we will ship to you for you to plug it into your router, or a software probe, which you can install and run on your own infrastructure. You’ll earn credits you can use for your own customised measurements.
