Could be badness in any part of the internet; could be at the BBC end. I imagine that the pipe into Downing Street and the nearby offices must be truly massive, probably an
ethernet 10G link or more. It surely won’t be ordinary FTTP because the upstream would be so awful, it would be a corporate type connection with symmetric goodness and with no contention with other local users as in ordinary domestic FTTP, if I understand domestic FTTP correctly?
I imagine that doing video conferencing with Australia might be horrible because of problems with the internet itself and the long fat pipe latency. But this was going wrong even before we got to that, wasn’t it?
I presume that Boris’s application was sending video packets which were QOS-marked as
high priority, because if not then some other flow, say even from an application running in Downing St or in the BBC could eat up all the bandwidth of the pipe. So perhaps it’s a rubbish video app that one or t’other end is using, which doesn’t use QoS properly?
