Which IPs that you use daily are actually affected by this though?

I've been trying to keep track myself and so far in my months of collecting, I've noted down one service which is unavailable during the matches for me, Docker Hub, everything else seems to work today.

Keep in mind, when they first started the blocks, a lot more was taken offline than what gets taken down when a match happens today, as they seem to continuously adjust it. The article you linked is from almost exactly a year ago, fwiw.
