If that is the case, why are they surprised when they cannot send e-mails or communicate with the outside world when the system goes down later in episode 3?

  • Just from a real-world technology perspective, it wouldn't be strange if they had a "main" internal network that was air-gapped from the internet, plus an "auxiliary" network that they used for email and stuff. – senshin Feb 21 '16 at 19:57

A network doesn't have to be public. Network is just a bunch of computers that are able to share their content between each other.

So they weren't able to communicate within their network nor with the outside world.

They probably could communicate to the outside world before through a proxy server that is within their control only.
