Sam Morduke,
I trust you are a technical consultant that can run iperf3 tests right? I really don't know why they can't request your help. I suggested them to contact you. They even have requested me if I can find a clients site that has gigabit bandwidth to see if I can run tests. I know the clients that are for sure affected aren't around since they are on vacation. Then there's a few sites that are unknown since I never bothered upgrading them to 200.7.x
I'm not even going to bother with the small school sites or larger sites..
