[swinog] Huge Packetloss towards switch mirrors?

[Benoit Panizzon]

Hi Community

Anyone else experiencing high latency and packetloss towards

ch.archive.ubuntu.com / mirror.switch.ch

IPv4 via SwissIX.
IPv6 via HE.

--- frisal.switch.ch ping statistics ---
99 packets transmitted, 34 received, 65% packet loss, time 99279ms
rtt min/avg/max/mdev = 425.674/601.445/705.015/62.817 ms

--- ch.archive.ubuntu.com ping statistics ---
21 packets transmitted, 7 received, 66% packet loss, time 20262ms
rtt min/avg/max/mdev = 531.911/594.194/645.790/43.318 ms

We've had a very strange issue with one of our ASR9Ks, which caused
loss and huge delays in the forwarding plane. A reload fixed it...

As the saying goes: any sufficiently advanced technology is
indistinguishable from magic.

Update: Switch just changed something in their routing.
No packet loss anymore from both source networks.

PING ch.archive.ubuntu.com(frisal.switch.ch (2001:620:0:1002::20)) 56 data bytes
^C
--- ch.archive.ubuntu.com ping statistics ---
14 packets transmitted, 0 received, 100% packet loss, time 13293ms

Here it's worse for IPv6 :-)
IPv4 indeed is fine now.
