Ok, interesting idea to actually think where to put the servers in a world like this.

In the story they’re used by the [netrunners/darkmovers/insert-underground-anticorpo-group] to communicate and post jobs and trade information without using the centralized corpo networks. Then, idk, a Cat6 hypercane in a +4C world takes out all of the established infrastructure and they’re quickly deployed across the ruins to get everyone back online.

This sounds very punky, anti-authorative. I was more thinking about the different communities that would develop if social networks work for building them instead of destroying them.
