The internet existed, with both ground lines and satellite based. Since the apocalypse, it has largely failed, but we need to be able to occasionally learn stuff from other hackers out there. We're kind of envisioning the old ham radio type community where some people could be in touch with others, but maybe not everybody and so information from distant locales was relayed word of mouth.

There is currently an effort to do internet over HAM radio for exactly this kind of situation. Let me know, I can hook you up with resources.
