[SLR4-SIXXS] Unable to connect to AS16276
![[fr]](/s/countries/fr.gif) Shadow Hawkins on Monday, 15 October 2012 18:43:14
Hello,
From this evening (7:00 PM CEST) I'm unable to ping and open connections to my IPv6 addresses in AS16276 (Ovh) from my tunnel T106110. I'm also unable to ping from my tunnel IPv6 addresses to IPv6 in AS16276 (Ovh).
Host behind AS16276 is a Debian GNU/Linux 6.0 Squeeze
Host behind my tunnel is an OpenBSD 5.1

Hello again,
I would add a ping to another host (not configured by me) in the AS16276.
From my sixxs tunnel to ipv6.ovh.com
# ping6 ipv6.ovh.com
PING6(56=40+8+8 bytes) 2a01:240:fe00:205::2 --> 2001:41d0:1:1b00:213:186:33:34
^C
--- ipv6.ovh.com ping6 statistics ---
186 packets transmitted, 0 packets received, 100.0% packet loss
From another AS (AS43646) to ipv6.ovh.com
$ ping6 -nc1 ipv6.ovh.com
PING ipv6.ovh.com(2001:41d0:1:1b00:213:186:33:34) 56 data bytes
64 bytes from 2001:41d0:1:1b00:213:186:33:34: icmp_seq=1 ttl=48 time=44.6 ms
--- ipv6.ovh.com ping statistics ---
1 packets transmitted, 1 received, 0% packet loss, time 0ms
rtt min/avg/max/mdev = 44.643/44.643/44.643/0.000 ms
I think there is some connection issue between AS16276 and AS30781.
Cheers,

Please contact OVH to fix their flaky network, nothing we can do about.

They probably fix their network. All seems back to normal. You can close. Thanks!

Hello,
I got the same problem yesterday (OVH on one side, MRS01 on the other side). And today, this is not fixed :

It seems to block at jaguar-network.com on both side, but I'm not a network expert.

Hop 7 in the first traceroute is OVH, they seem to lose routes once in a while and then fail to route properly. Contact OVH to resolve this.
