Cyberpunk 2077 features this reality. Its not discussed much, but basically only local small scale networking is done (like citywide scale) because the broader internet protocol has either crumbled or is polluted by adversarial bots. So its pretty taboo to go there or simply unused.

I'm sure someone else knows the lore better. There is a lot of supporting literature, just not a key component of any stories.

I think the lore is that the wider internet was intentionally taken down by a virus made by a master hacker in the past. Any attempts to connect with it gets you killed by either the virus or "feral ais", but some of the mega corps pay people to explore it every once in a while looking for stuff.
