BQM Gone Haywire

Hi guys

I have Sky FTTC (under the brand of NowTV) and I've noticed that as of yesterday my latency has gone crazy.

Here's a typical day (this was Thursday):
My Broadband Ping

Then yesterday it went offline for 3 hours. (I was out at the time fortunately):

Now I've got this:

Any idea what's cracking off?

Thanks in advance.

Looks like it got worse overnight between 10PM and 7AM. High max latency has turned into dropped packets (or so high they're exceeding the timeout maybe).

Need to look at your routers connection stats

Broadband Link Downstream Upstream
Connection Speed 40000 kbps 9605 kbps
Line Attenuation 20.5 dB 0.0 dB
Noise Margin 7.1 dB 6.6 dB

Stats are good, so suggests massive congestion and most likely something saturating your connection e.g. many Gigabytes of a cloud backup perhaps

Have you verified the latancy and packet loss with some out bound pinging, i.e. to ensure its not just delayed responses from the Sky Hub
