Bad connection to Facebook via IPv6

Shadow Hawkins on Thursday, 06 June 2013 15:10:47

Since a couple of days I can't reach Facebook.com over IPv6 any more. Other sites are fine. My browser tries to contact Facebook over IPv6 since it has IPv6 support, but that fails as pages take very long to load or don't load at all. Also, pings to Facebook are very high over IPv6:

ping6 www.facebook.com PING www.facebook.com(edge-star6-shv-03-frc1.facebook.com) 56 data bytes 64 bytes from edge-star6-shv-03-frc1.facebook.com: icmp_seq=1 ttl=51 time=296 ms 64 bytes from edge-star6-shv-03-frc1.facebook.com: icmp_seq=2 ttl=51 time=254 ms 64 bytes from edge-star6-shv-03-frc1.facebook.com: icmp_seq=3 ttl=51 time=249 ms 64 bytes from edge-star6-shv-03-frc1.facebook.com: icmp_seq=4 ttl=51 time=276 ms ^C --- www.facebook.com ping statistics --- 4 packets transmitted, 4 received, 0% packet loss, time 3003ms rtt min/avg/max/mdev = 249.499/269.104/296.168/18.622 ms

Pings over IPv4 to Facebook are fine though:

ping www.facebook.com PING star.c10r.facebook.com (31.13.64.1) 56(84) bytes of data. 64 bytes from edge-star-ecmp-01-ams2.facebook.com (31.13.64.1): icmp_seq=1 ttl=249 time=15.9 ms 64 bytes from edge-star-ecmp-01-ams2.facebook.com (31.13.64.1): icmp_seq=2 ttl=249 time=15.0 ms 64 bytes from edge-star-ecmp-01-ams2.facebook.com (31.13.64.1): icmp_seq=3 ttl=249 time=15.1 ms 64 bytes from edge-star-ecmp-01-ams2.facebook.com (31.13.64.1): icmp_seq=4 ttl=249 time=16.4 ms ^C --- star.c10r.facebook.com ping statistics --- 4 packets transmitted, 4 received, 0% packet loss, time 3004ms rtt min/avg/max/mdev = 15.082/15.659/16.488/0.590 ms

And pings to Google over IPv6 are fine too.

ping6 ipv6.google.com PING ipv6.google.com(wb-in-x68.1e100.net) 56 data bytes 64 bytes from wb-in-x68.1e100.net: icmp_seq=1 ttl=54 time=35.5 ms 64 bytes from wb-in-x68.1e100.net: icmp_seq=2 ttl=54 time=19.3 ms 64 bytes from wb-in-x68.1e100.net: icmp_seq=3 ttl=55 time=17.7 ms 64 bytes from wb-in-x68.1e100.net: icmp_seq=4 ttl=55 time=18.0 ms ^C --- ipv6.google.com ping statistics --- 4 packets transmitted, 4 received, 0% packet loss, time 3004ms rtt min/avg/max/mdev = 17.763/22.654/35.530/7.457 ms

I'm on nlams05, my username is LVF3-SIXXS, tunnel ID is T117018 and route ID is R214562. What could this be?

This was already reported in the forums and seems to be a problem on the Facebook side, hence it happens on all the PoPs. Facebook is aware of this and is investigating/resolving/etc.
