Using the same ISP from the same location, when pinging gw*.ibllc.com or cm*.esignal.com, at some days I get an average of 170ms and on some days an average of 600ms. I tried an alternative ISP I have and it's more or less the same.
This is no more controllable than the weather. Not much can be done about this imho.
