Dear all, The culprit for the high number of tests running on the RIPE Atlas platform would be me. I do apologize for not sending a notification prior to deploying the tests, we do understand that we are looking at quite a massive number of measurements. We are currently trying to slow down the rhythm of the traceroutes, in an effort to not be so aggressive. The purpose of the measurements is to establish the reachability of the limited-visibility IPv6 prefixes we were able to identify using the BGP Visibility Scanner. The measurements are a part of our efforts of enhancing our understanding on the results of the visibility tool for IPv6 prefixes. The RIPE Atlas team was kind enough to help us with our research and allowed us to use the Atlas platform. For more information about the BGP Visibility project, I kindly refer you to http://visibility.it.uc3m.es/ We've previously focused on the visibility of the IPv4 prefixes, please find a more detailed view on our results in the following RIPE Labs article: https://labs.ripe.net/Members/andra_lutu/the-bgp-visibility-scanner For any further inquiries, do not hesitate to contact us! I do apologize for any distress this might have caused! For the future, we will try to notify before deploying another large number of tests! Thank you, best regards, Andra
