The first post, i thought i sent a post last night but hey-ho it's possible it was lost in transit.
This morning it looks like you've seen there is an issue. I figured I'd supply some data, plus ask for some advice.
Area affected 20
Symptoms: upload speed dropping out for extended periods to < 1Mbs , the upload would be fine, 200 nearly but then drop down to half after 5 seconds (could just be traffic shaping that one - bursts to download small files etc).
This morning the speed tests are more positive BUT real-world testing of zoom showing I'm suffering network issues. I can hear them and see them fine but they complain I'm freezing and losing audio, which marries to last nights analysis.
