Twitch buffering

Having issues with any stream today on twitch, only watchable at 360p. I've rebooted all my equipment, with no improvement. My TBB graph is stable, and no packet loss or high latency seen.


Some sample IP's:

 

tracert 185.42.206.227

Tracing route to video-edge-c687b8.lhr03.no-abs.hls.ttvnw.net [185.42.206.227]
over a maximum of 30 hops:

1 <1 ms <1 ms <1 ms 172.16.1.1
2 11 ms 11 ms 15 ms 10.229.64.1
3 39 ms 37 ms 28 ms pres-core-2a-xe-810-0.network.virginmedia.net [82.19.157.225]
4 * * * Request timed out.
5 50 ms 54 ms 50 ms tcl3-ic-1-ae0-0.network.virginmedia.net [212.43.163.198]
6 reserved.justin.tv [192.16.69.42] reports: Destination net unreachable.

Trace complete.

 

The destination net unreachable is fine, it's just twitch blocking ICMP packets.

 

I "can" watch at 360p, but anything higher, it just buffers constantly.

 

This started today, 23rd Dec, and is usually fine.

Re: Twitch buffering

And also, speedtest.net is fine, 470Mbps down 30 odd up, fast.com is reporting 530mb down, so it's not a capacity issue locally. It's a problem between Virgin and twitch at that egress point in my traceroute.


Do note, everything else works fine, youtube, browsing, gaming, TBB graph as stated.

Re: Twitch buffering

Enabled my vpn (with Nord), and twitch works flawlessly. The issue is definitely with Virgin, please can you have a look.

Re: Twitch buffering

And then today, it's all been fine... Odd, I suspect it must have been just come peering congestion yesterday.

Tonight, to another server (same traceroute and exit)

Re: Twitch buffering

Quickly comparing, looks like there may have been congestion in Preston (ever so slight), 20ms increase in traceroutes.

Dunno, you guys have far more tools to monitor your network than I do 🙂

Re: Twitch buffering

Hi Nex,

 

Thank you for letting us know that things seem to have improved, I'm glad it's looking better 🙂

 

In taking a look at the backend of your services and the local network, I can't see any problems with your connections. It does look like there may have been some local congestion, but nothing to cause major concern.

 

How's everything been over the past few days? Any further issues or has it all been pretty healthy?

 

Thanks,

Rachael
