Title: Youtube/Facebook Video Slow/Buffering.
Post by: Napsterbater on February 07, 2018, 12:37:51 PM
Anyone else noticing issues with Youtube and/or Facebook video buffering alot more recently over HE IPv6 Tunnel?

This is on TServ13 Ash1 for me. Tunnel ID: 175140

Note Comcast IPv6 speed test show full 30+mbps (my ISP Subbed Speed) during the issues.

One of the Youtube/Google content servers having an issue, only 300-500kbps from it, r1---sn-vgqskn7z.googlevideo.com / 2607:f8b0:4009:3b::7

Edit: 2nd cotent server, r3---sn-vgqsknes.googlevideo.com   2607:f8b0:4017:32::8  only about 800kbps from it.

For the last couple of weeks I'm seeing the same behavior.  I'm don't think that it is limited to a single youtube host.  Here are the details of what I'm currently seeing:

Tunnel ID: 68971
Endpoint: tserv2.ash1.he.net (216.66.22.2)
Youtube host: r1---sn-a5meknek.googlevideo.com (2607:f8b0:401c:1b::7) 

Very slow to initial buffer, and then large drops in speed.  At times the stream will stop completely. 
I'm coming in from a 100Mbps FIOS connection.  No detectable issues on the IPv4 interfaces.

Been having the same issue here with tserv1.phx2 for the past couple weeks. No issues when toggling off IPv6 resolution in Firefox. I'm stringent with setting a max-mss on outgoing TCP traffic, so I don't think this is a local issue.

As a workaround for the time being I've added the following domains to the network.dns.ipv4OnlyDomains preference in Firefox's about:config and it appears to have mitigated the issue. 

youtube.com, youtu.be, googlevideo.com, ytimg.com

It also seems to affect Directv Now. I hate to give up static V6 as it's impossible to make Pfsense automatically update dynamic v6 hosts but with YT/DTV buffering all the time I have no choice.

Hate to say "me too", but "me too". Also on the Ashburn POP. YouTube is unusable through my IPv6 he.net tunnel.

Same problem here.
Using tunnel server: 216.66.22.2

As a workaround I have added *.youtube.com and *.1e100.net to my IPv6 DNS blacklist.
You can find more information about how I accomplished this if you refer to my thread here: https://forums.he.net/index.php?topic=3794

Can't tell, looks like comcast is throttling ipv6 traffic if I dont use native. I get full download speeds with native, but 1MBps when using HE tunnel.

They are not throttling. Congested link more likely.
