Just thought I'd add something - I just fixed my IPv6 tonight (forgot to save my switch VLAN configuration and had a power cut recently) and have been testing this via my IPv6 testing SSID, on wireless to my Chromebook along with my standard network SSID which currently has IPv6 disabled.

 

IPv6:

 

 

IPv4:

 

 

This is not at all scientific - heck I am testing this over WiFi on a Core M3 powered Chromebook but interesting that upload is not really affected.

 

Also, from what I have heard from people who work for 2degrees in their broadband and datacentre side it is still pretty-much Snap internally, and still based in Christchurch.

 

Also pinging @NickMack who may know something.

Hi All,

 

Testing has pointed us to the likely suspect - an issue has been identified with a change in behavior post a Junos upgrade on our core PE's - Change is currently in QA with the change scheduled to be rolled out today.

 

Nick.

@NickMack thanks very much! I do owe you beers next time I see you.

 

Seems resolved here:

 

 

(Same test, over WiFi, on my Chromebook - don't judge me!)

Can we get some more information about this issue..

 

When did it start (feels like it was like Nov/Dec last year)? What was it isolated to?

Sounds like the vendor made a change to the default beaviour.

 

BTW, fix works for me too.

Oh wow, I can use gfycat again. It's been months! And streamable!

 

 

 

I love you so much NickMack. I complained about this issue months ago, and after several reminders I was told that it went to the network team and they found nothing.

 

 

 

I guess that was a lie.

 

 

 

Anyway, thanks for the fix, late though it is.

That's why I'd like a bit more transparency here. Seems like a long term issue that affected quite a few people.

Hiya,

 

The issue affected some customers on ipv6 - based on the PE they were hitting and the revision of code they were hitting (We have a heap, and upgrading them takes time :-)). It has been escalated a few times from Care into one of my teams for investigation. Sometimes the description of a fault can lead you to troubleshoot in the 'wrong' area, this would be an example of this. We looked at the Queuing/QOS profiles for ipv6 traffic on old/new code and noticed a change in behaviour in some filters, which helped us isolate and resolve. Troubleshooting these issues sometimes takes time to Lab, reproduce and address/resolve.

 

Nick.
