20mbps... For the past few days, I buffer on YouTube ... Streaming on Kodi or any other live stream stops after 3 mins
Okay you should run your iperf less than your line speed to allow for overheads on the line. Try running it at 15M

An interface was being saturated in CPT since we implemented some new Longhaul. Have rerouted temporarily to resolve until we can upgrade the interface tomorrow. Apologies.

Thanks for the feedback, here are some tests since you've made the changes.

Upload still seems very low though? Although it doesn't bother me at the moment.

TCP window scaling on outbound connections with Windows isn't great.

And, it's better again. I'll add an mtr report next time it happens. I'm just frustrated with all the blips we're having on vuma / cool ideas the last few weeks. I work from home, and notice it immediately.

Line dropped and couldn't authenticate for a few minutes just now, of course just as I was trying to save something to an international server. Back now - hopefully just a blip?
