Thanks for letting me know those timestamps. I have gone ahead and enabled diagnostics mode for your account and what this action does is a set of logs will automatically be uploaded to our servers for analysis.
I’m looking over the log report now and I’m noticing something strange - it appears you’re also losing connection to our metadata servers around the same time the BBC stream drops off, and the stream looks like it was buffered.
Can you provide a full overview of your network including the model/manufacturer of your router and switches? I believe this could be related to how you have the network configured.
