Errors, could a VM have a look please.

I think there is external noise. The errors are intermittent and come in bursts.

    Their will always be errors and might have nothing to do with you which is what BQM is for

Update:- After months of mini dropouts and errors, I phoned the retentions line and threatened to leave. They put me through to technical who arranged a network engineer to investigate. Yesterday afternoon the network was down and expected completion in 12 hours. Back in an hour and has been up for 16 hours with zero errors, which I've not enjoyed for a long time.

  As it should be on a good circuit. Here's mine with an uptime of nearly two months ;-)

I spoke too soon. It's been on and off for the last hour or so. Upstream problems, many errors and missing channels.
