Dear RIPE Atlas probe and anchor hosts, We would like to share some information in light of the log4j issues that were recently made public. After an extensive investigation of our systems, we have determined that both the RIPE Atlas probes and the RIPE Atlas anchors are not vulnerable to the recently discovered log4j vulnerability. More information can be found in the official announcement: https://www.ripe.net/publications/news/announcements/log4j-zero-day-vulnerab... We wish you happy holidays and happy measuring :) Kind regards, Johan ter Beest RIPE Atlas Team
