YouTube terrible speed and buffering

Alecmac007

I am on Vodafone fibre so just under a year and no problems getting 10mbps but over the last 5 days I am getting terrible performance on YouTube on wifi on all devices. It either buffers, doesn’t play video and occasionally I get a period of a few minutes with no problems.

I have rebooted router and reset firmware and spoke to  Vodafone but no solution. If I connect to mobile data all is good, and all other streaming video sites work fantastic and my wifi speed is always good. Any ideas?

It's most certainly a service problem.

 

I have sent a DM to their Twitter as @Beth bad mentioned above so I guess will have to wait to hear back.

 

I don't feel like this is the same issue as the other thread. We're not talking 10ms latency, more like 30,000ms and the flat out refusal to communicate with certain Google servers for things such as installing play store apps.

 

It's tricky to know exactly which hosts to tracert as I can load YouTube/browse the catalogue or browse the play store just fine. The issue occurs only when trying to actually load a video download an app and especially with YouTube those hosts / URLs seem to be generated dynamically and different every time.

Everything just sits pending indefinitely unless connecting to mobile data or VPN.

I had problems streaming at the beginning of that thread too. I wanted to see what gateway you connect to as it's certainly not ideal to have your data travel the length of the country before it even meets the Internet backbone. At one point I was connected to a gateway in Ghana!

Interesting that you have the same problem, has it only recently happened?

I am based on Cirencester are you nearby or do you know any other people on Vodafone with a similar problem?

Spent over 1 hour with Vodaphone support to resolve but to no avail / not sure what else to try or to escalate further L


(third attempt to post this without the forum anti-spam deleting it!)

 

I'm in North-West Leeds. Openreach FTTC at the moment (FTTP is about 100yds away - so near, yet so far!)

The problem first started after we returned from a week's holiday, so it looks like something changed during W/C 22nd August as it was problematic from 26th August.

Unfortunately, I'm out of the country for a few days now so can't raise with support myself, but if it's still doing it when I get back, I'll raise a support ticket then. If you have a reference number I can share, feel free to message it to me so I can link them up.

 

Looking at the Chrome debug trace, I can see cancelled requests to <url1> (which also times out in the browser) but after 10-20 seconds, the youtube client then makes what I assume is a retry request to <url2>  which works ok (and return a successful 403 in the browser too). As speculated elsewhere, I suspect there is some sort of peering link broken causing intermittent, rather than terminal failures of requests between Voda and Google.


(URLs removed because Voda's daft board deletes the post if I include it - available here: https://pastebin.com/W1Zn8zPU)


I'm interested to see what other people with this problem get from the above URLs as this might help give a very specific problem to the Voda network team to resolve. Interestingly, the former URL doesn't work on VPN either, suggesting that there might be some Vodafone-specific infrastructure at Google that isn't very happy, and Voda customers are being explicitly directed to faulty infrastructure. I'm not familiar with how Vodafone manage their direct peering with Google, so this is speculation for me - perhaps others can answer this.

Requests timing out on first instance would certainly make sense for YouTube. I'm unsure of how this would affect play store as it's indefinitely.

Very odd behaviour. Makes me wonder how many people have actually reported it and how many are just assuming it's a YouTube problem etc.

If I had to guess - similar peering process going on to route traffic from Voda customers directly to Google, so same process, same symptoms, different service?

Oh, absolutely related. I guess I just meant that YouTube is able to send a video once the initial attempt has failed however the app downloads/updates for me never seem to "correct" themselves. Perhaps the delivery process is drastically different.

So glad I found this post, I have been having this exact same issue for about three weeks now. All devices in the house, resolved if using a VPN. The “Wi-Fi experts” refused to assist because I use my own router. Tried to explain its a routing issue their end given the VPN resolves it but they just kept saying that the only thing a VPN does is provide a different IP so YouTube must not like my IP!!! 

"The only thing a VPN does is provide a different IP" - Shocking!
I'm still waiting to hear back but I'm fully suspecting them to just write my experiences off because I use my own router too, though I do hope not.

The more people whom can raise this with them officially as an issue though, the better.

Tells you all you need to know about the knowledge of Vodafone "support". Useless.
