I didn't want to make a new thread for this so I'm just gonna ask it here.

I think I must have missed something so please remind me of this...

How exactly can the tech in Everkeep (which is located in the Source) communicate with the terminals in Living Memory (which is in the Ninth)? We see the regulators sending people's memories to Living Memory where they become endless, we also know that Calyx's terminal is located in the Ninth, yet he can project his image in Everkeep freely. However, every time we need to physically go to or come from Living Memory, we must do so through the portal in the Cenote.

Is Electrope WiFi capable of crossing the barrier between Source and the Ninth? Is this only possible because of the portal? What if the portal was closed?
