R'lyeh Dataserver

The HSMBC R'lyeh Dataserver is an underwater, "lights off" dataserver for tier 1 matrix routing services, with an expected operating lifetime of 10 years. It sees widespread use around the world to provide data coverage in remote regions, or as confidential wireless data services for private or corporate contractors.
The server can be paired with an external power source or utilize a built-in micro fusion cell, and is cooled by ambient water. It is designed to operate with no maintenance or human interference for over 10 years. Its flexible digital architecture automatically routes around faulty components. It has an underwater antenna that can receive and transmit data at distances of over 100 km.
The R'lyeh Dataserver is sometimes written as "Rlyeh" or "Relay", even in official documents.

Autonomous Physical Defenses

The R'lyeh Dataserver is protected by a Sea Locust submersible defense drone. The drone is fully autonomous and off-grid. The drone is pre-programmed to defend the server for its expected operating lifetime against all intruders, and there is no way to "turn off" the drone without physically neutralizing it.
The drone is designed to patrol the waters around the server. Primarily, it wards off marine life using visual threat displays or auditory cues. It is also equipped to interdict human divers from approaching the server using both nonlethal and deadly methods. It also recharges from an induction port located on the top of the Dataserver housing, on a randomized schedule.

Data Rights Management

R'lyeh Dataservers are equipped with an anti-tampering Data Rights Management (DRM) system. The server is able to deploy physical countermeasures against any entities approaching the server, up to and including a series of explosive devices designed to forensically destroy data housed in the server. The resulting underwater explosion is likely to also destroy the intruding entity.
The DRM system can be de-activated by a pre-encoded "Release Signal" sent via HSMBC satellites. These codes are closely guarded in the HSMBC HQ, and security measures require their transmission to be scheduled well ahead of time.
