I think it's natural for any community to be able to communicate with each other. After all RIPE Atlas is a community of networking geeks/nerds/engineers who like to measure the Internet and share resources with others. Sometimes we just need to exchange some info to get help and mailing lists is not always the best way to do it. I don't think it's a serious security threat but I also find comments from </span><span lang="EN-US">Martin Boissonneault quite helpful to build something as much secure as possible without excessive complexity.<o:p></o:p></span></p> <p class="MsoNormal"><span lang="EN-GB"><o:p> </o:p></span></p> <p class="MsoNormal"><span lang="EN-GB">When it comes to location of probes, </span> <span lang="EN-US">Steve Gibbard probably described the real problem more precisely than me. The goal is to get reliable data about probes location and this is for sure important for all RIPE Atlas users. One way is to poke people manually and it's OK if you have to do it once per few months but it would be better to get more automated detection mechanism for that. Steve uses IP geolocation which has its limitations (I know probes with IPs from country X but they are properly deployed and described in country Y on different continent). I personally visualize distance from probe to target and compare it with RTT and hops but it's still not fully automated and still can be tricky and requires additional checks.<o:p></o:p></span></p> <p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p> <p class="MsoNormal"><span lang="EN-US">So open question is: How to reliably verify location of probes OR How to motivate RIPE Atlas users to provide valid locations and keep it up-to-date?<o:p></o:p></span></p> <p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p> <div> <p class="MsoNormal"><span lang="EN-US">Regards,<o:p></o:p></span></p> </div> <p class="MsoNormal"><span lang="EN-US">Grzegorz</span><span lang="EN-GB"><o:p></o:p></span></p> <p class="MsoNormal"><span lang="EN-GB"><o:p> </o:p></span></p> <div style="border:none;border-top:solid #B5C4DF 1.0pt;padding:3.0pt 0cm 0cm 0cm"> <p class="MsoNormal"><b><span style="font-size:12.0pt;color:black">From: </span></b><span style="font-size:12.0pt;color:black">Robert Kisteleki <robert@ripe.net><br> <b>Organization: </b>RIPE NCC<br> <b>Date: </b>Wednesday 2019-04-24 at 10:43<br> <b>To: </b>"ripe-atlas@ripe.net" <ripe-atlas@ripe.net><br> <b>Subject: </b>Re: [atlas] Communication with probes' owners<o:p></o:p></span></p> </div> <div> <p class="MsoNormal"><o:p> </o:p></p> </div> <div> <p class="MsoNormal"><o:p> </o:p></p> </div> <div> <p class="MsoNormal"><o:p> </o:p></p> </div> <div> <p class="MsoNormal">On 2019-04-23 13:10, Ponikierski, Grzegorz wrote:<o:p></o:p></p> </div> <blockquote style="border:none;border-left:solid #B5C4DF 4.5pt;padding:0cm 0cm 0cm 4.0pt;margin-left:3.75pt;margin-right:0cm" id="MAC_OUTLOOK_ATTRIBUTION_BLOCKQUOTE"> <div> <p class="MsoNormal">I thought about simple web form available only for logged users of RIPE<o:p></o:p></p> </div> <div> <p class="MsoNormal">Atlas.
