Buffering issues on Youtube only

Hi All,

I wanted to pop together a quick community post to see if anyone else is having similar issues, There's a version of this post over on the BT Forum and EE Forum as well.

Since the beginning of June I've noticed that there's been a measurable increase in videos buffering, streams unplayable and videos downgrading in quality specifically on Youtube. Switching on a VPN instantly stops the issue from occurring. Interestingly it seems to be worse in the evenings but fine in the day.

I have 900mbps FTTP and have no issues whatsoever with speed and connectivity on other sites (streaming such as Twitch, no issues), I have spoken to PN support who have confirmed there's no line issues. I've disabled IPV6 so can rule that out, I've changed DNS so can rule that out. I've tried different devices and the issue persists across multiple devices. I use the PN provided Hub.

YT stats for nerds connection speed
Before connecting to a VPN: 9840 Kbps
After connecting to a VPN: 209389 Kbps

Digging in to the network tab I can see that the issues seem to stem primarily from the rr5---sn-cu-cime7.googlevideo.com GGC server, so potentially may be an avenue of investigation.

Cheers!

Well that's an interesting question.

As an example, at the moment stats for nerds for me gives 58151 Kbps connection speed at the moment (so quite enough for some HD video!).

I occasionally see a low resolution first few seconds on videos but I think that's probably coding by YouTube rather than a bandwidth limitation.
