YouTube buffering and other issues

YouTube is playing at 240p/144p and trying to install the F1TV app from the PlayStore been busy downloading for about 15 minutes now and only 33 minutes to go...

100/50 from Web Africa on VUMA Reach
 
I get the same issues, but only when using the Youtube app, i.e. streaming at 480 or below, when forcing it to go to 1080 it buffers (720 works ok).

If I use a browser, then it is fine, it automatically jumps to 1080 with no buffering problems. :unsure:

Vodacom Fibre

Also experiencing the same issue .. during the day it seems to be ok but towards the evening buffering begins but works 100% on mobile or via a VPN.

Will enabling ipv6 sort the issue out?
 
To give everyone an overview of what is happening and how Google traffic works this a brief explanation. I hope I'm not sharing too much but I think it's nice for clients to know a bit of background.

As an ISP you can get traffic from Google through peering at NAP in JHB or you can get some GGC caches deployed. Every ISP looks at traffic levels and see what they want to do to have the best performance. It's super convenient to have Google at JHB because all the traffic from Google is just 1-2ms away and with high capacity peering links that is a very good solution.

Google is experiencing some issues with capacity in JHB and started sending traffic elsewhere during the evening. This causes traffic to be served either from other edge servers from Google or public caches located around the world. It's a bit of a problem as everyone has noticed.

The other question people have been asking is why is it not buffering with Vodacom and MTN for example. Well the answer is simple. They have millions of subscribers and move a lot of traffic. They have likely invested a lot of cash to get a couple of google caches in all regions. That makes sense for them for the amount of traffic they move. As their subscribers watch more and more content they become available on the caches. They will also experience issues with uncached content but since they have so many subscribers that doesn't happen often. To test this you can load a couple of videos and check the IP's serving the content. They are usually all on-net servers.

What I have noticed is that there is a difference to IPv4 and IPv6 traffic from Google. During the evening peak Google starts sending IPv4 traffic elsewhere. IPv6 is still mainly served from jnb but at around 8pm or so they shift that also on. IPv6 seems to come from Kenya which is around 65ms or so away while IPv4 bounces around the globe from Sydney, Tokyo, London, Paris and Amsterdam.

If you have access to IPv6 I would suggest switching that on as it seems that due to low IPv6 adoption in Kenya, Google deems enough capacity available there to serve traffic from there.
 
Awesome .. thanks for the detailed explanation cavedog
 
A quick ping to google.com should confirm
Works and then stops working, unreachable destination... pinged google.com on 3 different machines, 1 wired, 2 wireless, all running windows 11... first attempt earlier they all worked, now they all failed, rebooted router - all worked, 5 minutes later all fail with the "destination net unreachable error message. Weird hey?

What am I missing here? Can't ping anything other than my router?

Internet is working as it should though despite this...

Uhm okay double check these settings.

Get ipv6 : DHCPv6
Prefix delegation : enabled

Under the LAN section change it to DHCPv6.

Save those settings and see if that fixes the issue.
 
Great. See if that improves you YouTube experience.

Due to the capacity issues even google drive is currently suffering from the same issue.

Buffering this evening. Also destination unreachable on the ping…
