jitters up to 1000ms because of akamai.plix.pl

The issue is always reproducible. I always see jets up to 1000ms if anything happens around (usually around 500). Both on big or small maps.  I started to notice it after latest update related to a new season. Before this mostly everything was fine. Please advice what to do.

Screenshots with networking and performance (the issue reproducible from low to high graphic settings, really not related)

Two trace routes with game running and game off (just in case).
