High amounts of ping lately?

I’ve just had a game in QPC and kept an eye on the latency. It was jumping from 50ms to 185ms - it was very nearly unplayable. Other players noticed I was “shaking”. Is there a way to track the latency server connection and report the log to Blizzard? If It’s a my end I can get onto my ISP (Virgin Media)…

((Update)) I followed the guidance here to flush my DNS and it sort of helped. I still had a few moments where I was strafing due to high latency, but it wasn’t as frequent as before.
