Try behind a VPN or change your DNS server

Paul 27-05-2026 18:53

Re: Youtube buffering issues
 
Those traces look fine and they dont indicate any VPN in use - the DNS seems to have looked up youtube just fine.

Did this start last night? There is currently a network fault in Swansea. Do you know which hubsite you are connected to?

Corey N Georgie 28-05-2026 02:04

Re: Youtube buffering issues
 
how would I find out what hub site I'm connected to?

Jaymoss 28-05-2026 06:25

Re: Youtube buffering issues
 
If you are with Virgin click connection top of the page

OK, that's Cwmbwrla. You are very likely affected by the outage.

No buffering issues using Private Internet Access VPN.....

So it must be the way VM is routing its traffic?

Well it is often something on the route. Seeing the trace and it looking fine does not mean there is not an issue on it. You send out tiny packets and receive it back it is nothing like the through put needed for streaming. TBH running a tracecert on a site you know you are reaching but it is buffering is not going to show you much because you already know you are getting there. Pinging the site might give you more clues if there is delays and packetloss

When I have issues I always try behind a VPN first to see if it is a route issue and keep my primary DNA to google and Secondary to Cloudflare. Dunno if this helps much but I do it anyway

The buffering issues don't seem to happen at night.

I'm watching YouTube videos fine at the moment.

Would have thought if it was a load issue then it would be opposite.

If it is all still find behind a VPN then you know it is something along the way and by bypassing it you fix it . What about other streaming sites ITVX iPlayer Netflix Prime testing these will give you more clues

Personally, I just think it's Youtube.

Sometimes I'll watch a video that 'buffers', I know it's not my connection so probably down to the 'quality' of the video.

it works fine behind a vpn

I got 2 different connections one openreach and one 5G and various sites respond differently on them on the same machine and on the same browser on the same day around the same time. Weird things happen along the way

Netflix works fine.
It seems to work fine behind a VPN.

so it is something simply along the way

Re: Youtube buffering issues
 
Surely Virgin must be aware of the issue I doubt its just me having the issue.

Jaymoss 04-06-2026 13:34

Re: Youtube buffering issues
 
it might not be anything to do with Virgin they are just the first bit of the line

Think of the world wide web and imagine getting from one place to another all the connections and data lines and if ya 5G link me thin air from tower to tower to line and so on

The whole thing is freaking immense you sent my train of thought down a rabbit hole now haa

Corey N Georgie 04-06-2026 15:53

Re: Youtube buffering issues
 
What's the best way of finding out what it might be?

Jaymoss 04-06-2026 16:58

Re: Youtube buffering issues
 
Honestly you can't . You have ruled out your end with it working with a VPN and Netflix works without it so it is not you. It is not youtube because it works behind you VPN. It could be Virgin (but your net appears fine)or it could be anywhere along the route. It will likely just get better when they stumble upon it

OK thanks for everything guys.
