Hello, I noticed that f.root-servers.net is unreachable via IPv4 from my test locations (most of them in Germany). Relying on RIPE ATLAS [1] I'm pretty sure I'm not alon with this "problem".
A traceroute from my home DSL connection (DTAG, AS3320) shows that packets are surprisingly routed to somewhere in Pakistan and never get answered. Also Port 53/UDP/TCP is unresponsive. --------------------------------- traceroute to f.root-servers.net (192.5.5.241), 30 hops max, 60 byte packets 1 87.186.224.133 (87.186.224.133) [AS3320] 18.144 ms 2 87.190.177.174 (87.190.177.174) [AS3320] 18.843 ms 3 217.239.49.30 (217.239.49.30) [AS3320] 23.291 ms 4 te0-0-0-16.agr21.fra03.atlas.cogentco.com (130.117.14.149) [AS174] 33.528 ms 5 * 6 be2959.ccr21.muc03.atlas.cogentco.com (154.54.36.54) [AS174] 38.948 ms 7 be3072.ccr21.zrh01.atlas.cogentco.com (130.117.0.17) [AS174] 41.687 ms 8 be3080.ccr21.mrs01.atlas.cogentco.com (130.117.49.1) [AS174] 46.415 ms 9 be2345.agr21.mrs01.atlas.cogentco.com (154.54.38.170) [AS174] 46.891 ms 10 ptcl.demarc.cogentco.com (149.6.155.146) [*] 156.865 ms 11 static-10GE-KHI275-P01-SwA.pie.net.pk (202.125.128.173) [AS17557] 155.095 ms 12 221.120.251.178 (221.120.251.178) [AS17557] 153.854 ms 13 * 14 * 15 * 16 * 17 * --------------------------------- Has something happened to the F-Root instances in Europe?
