Newbie needs help interpreting BQM

Hi, I am on Virgin Media's 200 mbps package and utill Thursday was getting a rock solid 11/220/12. Then I noticed all speeds have dropped to around 15/40/11. Not getting any dropouts. My BQM was great until then - see first link, but last few days it is clearly problematic - second link. I will call it in in a day or so if it doesn't improve - but you will all be aware of the notorious behaviour of their "offshore" CS agents, so I want to go in with some informed comment to back up my simple "I think I have noise on my line". Thanks for any input

Noise on the line is a DSL thing not a cable broadband thing

The sharp cliff edges to the poor BQM suggest that you might be doing something yourself to saturate the upstream e.g. a large cloud backup, or are downloading multiple massive files.

If this was congestion in the local area you would not expect such an on/off behaviour

Thanks for the input I will check out the download/upload activities. Re. "noise" - although we may be talking about different things, the SNR (Signal Noise Ratio) is an important measure of the cable modem and connection performance - there are hundreds of posts about "noise" on the line contributing to speed reductions and drop outs on the VM Networking forum. There is an extremely detailed and technical overview of this, that is way over my pay grade, here...
