GMail IPv6 IMAP Issue, or is it Just Me?

Is anyone else having issues reaching GMail on IPv6 via IMAP, or is it just me? Here's some of what I'm seeing: It responds to ping... imac01:~ branto$ ping6 imap.gmail.com PING6(56=40+8+8 bytes) 2001:470:8d30:b00c::bb0e --> 2607:f8b0:400d:c00::6c 16 bytes from 2607:f8b0:400d:c00::6c, icmp_seq=0 hlim=55 time=31.299 ms 16 bytes from 2607:f8b0:400d:c00::6c, icmp_seq=1 hlim=55 time=41.528 ms 16 bytes from 2607:f8b0:400d:c00::6c, icmp_seq=2 hlim=55 time=30.092 ms 16 bytes from 2607:f8b0:400d:c00::6c, icmp_seq=3 hlim=55 time=35.450 ms ^C --- gmail-imap.l.google.com ping6 statistics --- 4 packets transmitted, 4 packets received, 0.0% packet loss round-trip min/avg/max/std-dev = 30.092/34.592/41.528/4.470 ms TCP Sessions on v6 seem to time-out: imac01:~ branto$ telnet -6 imap.gmail.com 993 Trying 2607:f8b0:400d:c01::6c... telnet: connect to address 2607:f8b0:400d:c01::6c: Operation timed out telnet: Unable to connect to remote host IPv4 Connects: imac01:~ branto$ telnet -4 imap.gmail.com 993 Trying 173.194.76.108...

Anyone from O1?
by Robert Glover 01 Jun '13

Anyone from O1 around? Your support line (888-444-1111) is failing to "All Circuits are Busy". Managed Modem service numbers in Area Codes 530 & 916 are failing to "All Circuits are Busy". Any ETA for service to be restored? I have some grumpy dial-up users this morning. -Robert

Headscratcher of the week
by Mike 01 Jun '13

Gang, In the interest of sharing 'the weird stuff' which makes the job of being an operator ... uh, fun? is that the right word?..., I would like to present the following two smokeping latency/packetloss plots, which are by far the weirdest I have ever seen. These plots are from our smokeping host out to a customer location. The customer is connected via DSL and they run PPPoE over it to connect with our access concentrator. There is about 5 physical insfastructure hops between the host and customer; The switch, the BRAS, the Switch again, and then directly to the DSLAM and then customer on the end. The 10 day plot: http://picpaste.com/10_Day_graph-YV3IdvRV.png The 30 hour plot: http://picpaste.com/30_hour_graph-DrwzfhYJ.png How can you possibly have consistent increase in latency like that? I'd love to hear theories (or offers of beer, your choice!). Happy friday all! Mike-
