WhoWhatWhen
brycec<.<

Huh, my network seemed to glitch out for a bit there.
[14:28]
mercutiojust to arp, or in general? [14:29]
brycecMy ssh to ARP timed out
(on a call so can't dig into it)
[14:37]
mercutioahh [14:37]
brycec(and I tried reconnect and it timed out) [14:37]
mercutiothat's even more disconcerting [14:38]
.... (idle for 19mn)
brycecheh
For all I know, it was my home IPv4 or v6 connection
Though Smokeping suggests it was ARP-side...
[14:57]
Looks like HE's v6 routing is b0rked, mtr from my home to my VPS' v6 address gets stuck at 10ge13-4.core1.sjc2.he.net
Or maybe not HE, mtr from my VPS back to my home v6 address is going over ntt.net and gets stuck at ae-40.r02.snjsca04.us.bb.gin.ntt.net
[15:05]
staticsafeasymmetric routing o/ [15:07]
brycechttp://sprunge.us/bBUY to clarify
Yep, and asymmetric routing is fine... as long as it works :p
[15:08]
mercutioi'd suspect he.net over ntt normally
but from that mtr you can't really tell where it's going wrong
tcpdump shoudl be able to tell you if it passes traffic in one directoin
[15:10]
brycecSorry :)
Oh yeah, sure
[15:11]
mercutioarp can't reach www.he.net atm [15:12]
brycecConfirmed my home->vps ping was received at the vps, and replied to
(haven't tcpdump'd my end of the HE tunnel)
yeah mtr to he gets stuck in ntt.net
(And confirmed, no response received at my end of the tunnel)
So... blaming ntt
[15:13]
mercutioyaeh or ntt to he.net
is it working better now?
[15:19]
brycecYes!
(I see you, or someone, changed the return route)
[15:23]
mercutiome
he.net was dropping out before though, let's hope it doesn't now :)
it's still a mystery why ntt->he.net would suddenly break

brycecI know, let's switch to Cogent! /s
(I assume Cogent/HE still haven't kissed and made up)
[15:28]
mercutioyeh don't think so [15:31]
***mnathani has joined #arpnetworks

mercutiontt's looking glass suggests it goes ntt -> telia -> he.net
so it maybe it didn't failover very quickly
the AS path length is still saying 2914 6939 (ntt he.net)
err minus length :)
oh ntt is down again now though
[15:32]
brycecmercutio: Thank you very much for the quick response :) [15:42]
mercutioyou're welcome
but i'm still curious what happened :)
