With your help, the RIPE NCC is building the largest Internet measurement network ever made. RIPE Atlas employs a global network of probes that measure Internet connectivity and reachability, providing an unprecedented understanding of the state of the Internet in real time.

Recent News

Due to an unfortunate bug in a recent probe firmware (version 4760), TCP based DNS measurements are not providing correct results. This affects all ongoing and one-off measurements.

The issue also affected DNSMON measurements between 14-23 March. On 23 March we deployed a corrected firmware on RIPE Atlas anchors (version 4770), and in the near future we'll deploy it on regular probes as well.

Our excuses for the inconvenience caused!
