Dear colleagues, We are currently in the process of shutting down our Test Traffic Measurement Service (TTM). These plans were previously announced at RIPE 64 by Daniel Karrenberg in the Measurement Analysis and Tools (MAT) Working Group session, and in section 2.4.5 of the RIPE NCC Activity Plan and Budget 2013: http://www.ripe.net/ripe/docs/ripe-558 This is now scheduled for completion by the end of the first quarter of 2014. The TTM service has been operational for more than ten years. The equipment used to provide this service, as well as the software underlying it, have become outdated and costly to maintain. Several years ago, we introduced our new measurements service, RIPE Atlas. RIPE Atlas and RIPE Atlas anchors can provide almost all of the functionality provided by TTM. This was explained by Kaveh Ranjbar, the RIPE NCC's Chief Information Officer, in the RIPE Labs article, “The Future of RIPE NCC Technical Services”. As noted in this article, one difference is that RIPE Atlas does not support one-way latency measurements; however, these were not used by most TTM users and also required special, expensive equipment. The article is available in full at: https://labs.ripe.net/Members/kranjbar/future-of-ripe-ncc-technical-services We will contact individual TTM hosts shortly to make arrangements to decommission their TTM systems. We are also investigating the possibility of creating an archive of TTM measurement results that can be used for research purposes. As previously mentioned, RIPE Atlas, and specifically RIPE Atlas anchors, provide much of the functionality of TTM. More details about the features and benefits of RIPE Atlas anchors, including information about how you can host a RIPE Atlas anchor, are available at: https://atlas.ripe.net/about/anchors/ We look forward to any feedback or questions you may have regarding this development. Regards, Romeo Zwart Global Information Infrastructure Services Manager RIPE NCC
