I have a M350 Fibre Broadband package. Every so often I've noticed that my upload speed drops significantly to very slow speeds (speed test websites report around 0.05Mbps to 0.30Mbps upload, even had a 0.00 once but not sure I believe that) however my download speed seems to be completely unimpacted, the majority of the time my download speed can exceed 350Mbps
I've created a thinkbroadband monitor this morning so it is still populating
