Details

I chatted with James about this last week but didn't have good data showing it. It started happening again this morning and I got some data. The symptoms are certain websites are slow while others are fast. The common element between the slow sites is that they have IPv6 DNS and interfaces (e.g. google, and youtube) and our IPv6 enabled office uses those paths. The unaffected sites are IPv4 only sites. While watching a youtube video it started to have buffering problems. Obviously in our 50Mbps office with a wired connection to youtube, this shouldn't happen. I ran an ipv4 and ipv6 ping to youtube and saw this : Here's the ipv4 ping to youtube, which looks normal gene@wendy:~/Downloads/CrashPlanPROe-install$ ping www.youtube.com PING

James here's some data on that event I reported last week.
Assignee: network-operations → jbarnell
Adding to the bug - I helped a user with an X240 Windows 8.1. She was experiencing the wi-fi connected as "limited." I disabled IPv6 on her machine. It fixed the issue and she was fully connected as expected. This was on the 3rd floor near wap303.
Gene -- how about pinging something local with IPv6, to determine whether it is a local problem or a problem in someone else's network?
Flags: needinfo?(gene)
:dcurado, would it be possible for you to set your SF office network monitoring (smokeping?) to do this check? Or would it be possible for netops to investigate this by setting up temporary monitoring from a host in SF (e.g. James' laptop or netops gear in SF)?
Flags: needinfo?(gene) → needinfo?(dcurado)
crimeny, I'm just saying next time you see this, maybe do an mtr instead, or ping6 the local gateway so we can see where the problem actually is. Skip it. We'll figure it out.
I"m closing this but. We've replaced 100% of infrastructure. Since that point I haven't seen or heard of problems.
