We have disconnected peers who were (repeatedly) not obeying the law or the DE-CIX Terms and Conditions. I gave a talk about what DE-CIX does in this regard during RIPE75 (<a href="https://ripe75.ripe.net/archives/video/103/"><span style="color:#0563C1">https://ripe75.ripe.net/archives/video/103/</span></a>).<o:p></o:p></p> </div> <div> <p class="MsoNormal"> <o:p></o:p></p> </div> <div> <p class="MsoNormal">Disclaimer: I am not a lawyer.<o:p></o:p></p> </div> <div> <p class="MsoNormal"> <o:p></o:p></p> </div> <div> <p class="MsoNormal">The European telecommunication law does not allow IXPs to look into peers' traffic on the application level (for a good reason, I believe). So, we do not know if a peer hosts malware or is sending out spam only. DE-CIX is only allowed to look into the operational data (e.g., Route or ASN hijacks) or behavior (e.g., unwanted traffic due to static routes on the Peering LAN). Based on this information, DE-CIX is acting.<o:p></o:p></p> </div> <div> <p class="MsoNormal"> <o:p></o:p></p> </div> <div> <p class="MsoNormal">I am highlighting this because I see issues if IXPs (or carriers and transit providers) are used as central infrastructure to filter data due to information they cannot verify or generate.
