Cogent LA issues

Recently it seems like anything that travels through te0-7-0-30.ccr41.lax04.atlas.cogentco.com is getting packet-loss and slowness. Is anyone else experiencing this?

Covering prefix blackholing traffic to one of its covered prefixes....
by Steven Wallace 24 Apr '17

24 Apr '17

We have dual-homed sites that only accept routes from their peers, and default to their transit provider. A site may receive a covering prefix from a peer, but since they are not accepting the full table from their transit provider they don’t see the covered (i.e., more specific). In some cases the peer announcing the covering prefix blackholes traffic to the covered prefix. Is this accepted behavior, or should a peer announcing a covering prefix always delver packets to its covered routes? Does this happen often? Thanks! Steven Wallace Indiana University

Amazon EU-West 1 trouble
by Baldur Norddahl 23 Apr '17

23 Apr '17

Hello, We are currently experiencing massive packet loss from Amazon EU-West 1. This page http://ec2-reachability.amazonaws.com/ will show most of eu-west-1 as down but actually it is packet loss of 90+ %. I have found that if I shutdown our link to Hurricane Electric the problem disappears. Also it is only an IPv4 problem as IPv6 is fine (also going through Hurricane Electric). A traceroute shows everything ok until the first hop inside the Amazon network. The peering is apparently at AMS-IX. Right now we are ok because I am keeping the HE.Net connection down, but I managed to find another NLNOG Ring node that has the same problem: gigabit@casablanca01:~$ ping 52.16.0.2 PING 52.16.0.2 (52.16.0.2) 56(84) bytes of data. 64 bytes from 52.16.0.2: icmp_seq=2 ttl=244 time=35.1 ms 64 bytes from 52.16.0.2: icmp_seq=34 ttl=244 time=35.2 ms 64 bytes from 52.16.0.2: icmp_seq=44 ttl=244 time=35.2 ms 64 bytes from 52.16.0.2: icmp_seq=52 ttl=244 time=35.2 ms ^C --- 52.16.0.2 ping statistics --- 72 packets transmitted, 4 received, 94% packet loss, time 71228ms rtt min/avg/max/mdev = 35.170/35.220/35.251/0.232 ms That IP is one from eu-west-1 taken from the ec2-reachability page. When I ping it with the HE.Net link down there is 0% packet loss. With it up we are seeing something like the above. However I notice that Casablanca is going out through Telia not HE. The return path could very well be via HE of course, there is no way to know that. From all the RING nodes I checked only Casablanca01 seems to experience the problem, so it appears it is not very wide spread. Anyone know how to get in contact with Amazon and have them debug this issue? Regards, Baldur
