YouTube Buffering and Slow Loading on BT Full Fibre 900 – Possible Routing/Peering Issue

@Azileo Interesting, maybe they're working on it currently or it was just sheer luck of the draw

I'm not connected to the VPN right now so will keep an eye out through the evening

We’ve narrowed it down to 2 badly behaving caching servers but were unable to pinpoint the exact failure cause (ruled out routing, capacity, peering, bandwidth etc) so have taken traffic away to fallback sites whilst we investigate more. It may take a little while to fully drain them but hopefully improvements will be seen

Thanks @Steve_M good to hear

rr4---sn-cu-c9i6 seems to be behaving nicely, currently sitting at a stats for nerds speed of 46965kbps whilst far lower than my actual download speed, it's performing much better and doesn't immediately buffer and auto-negotiate the resolution down.

@tyencyuI'm seeing throughput levels similar to what you're currently experiencing. Live streams are no longer buffering or freezing every few seconds, which indicates that mitigation measures are being implemented. Although my connection is still performing well below its normal baseline and hasn't yet returned to expected speeds, there are clear signs of improvement, suggesting they're actively working to resolve the underlying issue.

@Steve_M It seems to be pretty much fixed for me now. Thank you for passing all of this information on. I'll keep a close eye on things and report back if anything changes. @tyencyu can you confirm if everything is running smoothly on your end incase it is just a fluke for me.

@Azileo Yeah all good here, I can actually watch YT streams again without it buffering every 5 seconds

@tyencyu  brilliant news, well done too everyone for helping 🙂

Concur, watching 2160p vids without issues tonight. 

Maybe bt could implement some monitoring to prevent this from happening again??

Reading these posts it looks like it might be fixed? I can’t check until Thursday next week as I’m on holiday.

but thanks for all you guys helping and supporting with this issue.

We’re very confident we understand what was happening and are reintroducing the two sites with a different configuration. Will monitor very closely but if you spot it going downhill before I do then you know where I am 🙂
