Dear MAT WG, the time has come to make my “Chair” vacant and bring some fresh blood into the MAT WG:-) As you might remember I am one of original three MAT WG CoChairs since the MAT was rechartered out of the original Test Traffic WG at RIPE60 in Prague. Originally I was chairing together with Ian Meikle and Richard Barnes which left over the years and where eventually succeeded by Nina Bargisen. (Job description for interested Candidates:-)) I have done the job now for 7,5 years prepared the session, chaired the session, answered emails, welcomed new attendees at RIPE Meetings, represented the WG at ENOG and sometimes other conferences, had countless conversation with Daniel, Robert, Kaveh and of course Vesna about RIPE Atlas and the Anchors and about further and future collaboration. Attended RIPE Hackathons. Participated in the PDP review and in the WG collective as your representative, etc. These are all tasks a MAT WG CoChair does do to one or the other degree, and which you should be interested in if you apply for it. In the last years we came up with an election process which was approved by you and used when we elected Nina and which I want to use now for replacing me. We will go through the process as described below and ideally present the new WG CoChair at the next WG Session in Dubai. After the Dubai Meeting I will then officially step down. The process: 1. A call for interested parties is made on the WG mailing list at three yearly intervals, or as needed 2. Interested parties have 2 weeks to make their interest known via the mailing list 3. The MAT-WG chairs issue a call for discussion as per normal. WG members express their approval or otherwise of the presented candidates. 4. After two weeks the chairs declare consensus as they would do for a policy proposal As a remainder our Charter and Website can be found at: https://www.ripe.net/ripe/groups/wg/mat <https://www.ripe.net/ripe/groups/wg/mat> and the official Job description at: https://www.ripe.net/ripe/docs/ripe-542 <https://www.ripe.net/ripe/docs/ripe-542> Please feel free to nominate yourself if you are interested or shanghai others ( with their approval:-)) till the 11th September. Thx a lot and it was a pleasure to serve you. Christian Kaufmann MAT WG Co-Chair PS: I want to thank the RIPE NCC for their support over all the years, without them there would be no MAT WG, especially Mark Dranse who inspired me to start this journey, Daniel for starting RIPE Atlas and his vision, Rob B. for his wisdom as RIPE Chair, Robert and Kaveh for their never ending support and input, Vesna for her spirit and energy and for bringing so many people together, Amanda for the minutes and Hans Petter for doing an excellent job as a WG Chair Dompteur. And last but not least Nina for continuing the WG and her support in the last years.
