Today, I discovered by accident that my #ISP that is exclusively active in #Germany doesn't have a direct peering link to #DTAG. While #BGPTools aggregation graph can be trusted, I tracerouted a few connections to some known DTAG services. My packets always route over #Zayo. For me, it was a surprise to discover that my ISP with over 300 /24 IPv4 networks, doesn't have a direct peering agreement with the largest German network. #routing #bgp
