Hi Cerezer,
This is Wil, one of the independent advisor and an expert with Windows 10.
I understand your concern with spiking ping.
Ping actually can be caused by an intermittent issue on your internet connection. Is the first time that you experienced this issue?
I hope that you can reply back as quickly as possible so I can help you out further. Have a nice day.
Thanks,
Wilfred P.
