I last worked at JPL 10 years ago but all mission systems lived on many distinct networks of “dark cable and fiber”. Physical access to mission networks was usually heavily guarded. It would take accessing several doors to just be in a room with a network drop or telco closet. Access in any of cafeterias (there’s more than 1) over WiFi is limited to common systems and the internet. There was no Cat5/6 in the cafeterias. There was also a further limited Guest WiFi network for media, guests and the like with bandwidth limited access to the internet only.
