How do you find out which PS4 games are losing online servers?

sony doesn't keep one list, it's down to each publisher, which is the annoying part. the big ones post their own schedules. EA and ubisoft both keep a running page of games losing online services with the dates, and smaller publishers usually announce it on their socials or in a patch note a few months ahead. quickest check for one game is searching the title plus servers shutting down. and if it's a sports game more than a few years old, assume it's already on the list.
