These domains on a Blizzard's game website

I entered playoverwatch.com (website for Blizzard’s Overwatch game) for the first time in a while and I saw it connecting to this domain:

http://d.xp1.ru4.com/
20658635p.rfihub.com

I did some quick Googling to see if people knew what these were, and there were lot of Battle.net user posts from couple years back, some claiming these to be normal trackers/advertisers, and some claimed them being malware/browser hijacks.

I checked Avast Online Secyrity for that page and those domains stopped loading once I disabled trackings.
