the point is: Level3 is exporting this prefix to the EU since ~1 week Telia is learning it from Level3 and they also started to re-export it: Telia Looking Glass (http://lg.telia.net/?query=bgp&protocol=IPv4&addr=31.13.71.0/24+exact&route r=Vienna) Command: show route protocol bgp 31.13.71.36 table inet.0 31.13.71.0/24 *[BGP/170] 18w5d 16:40:16, MED 0, localpref 150 AS path: 3356 32934 I, validation-state: unverified > to 80.239.128.178 via ae9.0 This is causing >120ms latency to Austrian (and some German ...) networks towards Facebook - current traceroute from source network 188.172.239.0/24: Packets Pings Host Loss% Snt Last Avg Best Wrst StDev 1. router 0.0% 4 0.5 0.5 0.5 0.6 0.0 2. 192.168.8.3 0.0% 4 0.6 0.7 0.6 0.8 0.1 3. 37.252.236.88 0.0% 4 37.3 34.2 30.6 37.3 2.9 4. er-03.00-09-23.anx04.vie.at.anexia-it.com 0.0% 4 21.1 31.9 21.1 50.9 13.3 5. cr-02.0v-08-72.anx03.vie.at.anexia-it.com 0.0% 4 23.2 25.9 20.4 31.6 5.1 6. win-b4-link.telia.net 0.0% 4 22.1 25.0 22.1 30.1 3.5 7. level-ic-1573273-wien-b4.c.telia.net 0.0% 3 22.4 22.3 21.1 23.3 1.1 8. ae-3-3611.edge2.dallas1.level3.net 0.0% 3 150.5 150.6 150.4 150.8 0.2 9. facebook-in.edge2.dallas1.level3.net 0.0% 3 156.6 152.9 151.0 156.6 3.2 10. po102.psw02.dft4.tfbnw.net 0.0% 3 151.4 151.6 151.4 152.0 0.4 11. 173.252.67.57 0.0% 3 151.6 152.3 151.6 153.4 0.9 12. edge-star-mini-shv-01-dft4.facebook.com 0.0% 3 159.3 158.4 152.5 163.6 5.6 The admins of AS42473 started to drop the more specific from Level3 and now they get it from Telia (which is the Level3 re-export they learned). I guess you guys should talk to Level3 and ask them what the hell they are doing? :). Thanks & best regards Jürgen
