Chronic reduction of BB quality (a month on)

Hi

Having messaged four or five different VM reps via secret message and two tech visits I have gotten nowhere. The reps have done their jobs and 'escalated' the problem but nobody above them has contacted or acknowledged me. Today I noticed another series of latency/dropout episodes and took a quick snapshot of the Hub 5 readings. Can someone have a look and see if there is an obvious problem so that I might help them to help me? I think the Post RS errors are large? There are also lots of 'warning' and a 'critical' in the log too.

Thank you
John
