Pathweb

The Pathweb, also known as the command network (AUDIO: Jubilee) the Dalek galactic webwork, (PROSE: The Quantum Archangel) and the Dalek hive mind, (TV: Twice Upon a Time) was the shared intelligence of the Daleks, containing information on their history and experiences. It was more an artificial telepathic link than a true hive mind; (TV: Asylum of the Daleks) the Sixth Doctor described it as "artificial telepathy between Daleks," (AUDIO: The Curse of Davros) and when he compiled a list of supercomputers, he included the Dalek Emperor because it was connected to the Dalek galactic webwork. (PROSE: The Quantum Archangel)

Using the command network, one Dalek could contact all others to share information. (AUDIO: Jubilee) Susan Mendes and Kalendorf were able to hack into the Dalek Emperor's command network and cause all Dalek technology to self-destruct, creating the Great Catastrophe. (AUDIO: Dalek War: Chapter Four)

During the Kotturuh crisis, when the Eighth Doctor and the Dalek Prime Strategist were exploring the records of Wrax, the latter gave the former a communication device to keep them connected through the Pathweb. When the Wraxians aimed to turn the Devolver on the Dalek Time Squad, the Dalek Time Commander contacted the Dalek Executioner through the Pathweb to order the extermination of the Wraxians. (AUDIO: The Enemy of My Enemy)

The War Doctor explained the Pathweb was how Daleks communicated with each other. Having altered the Pathweb signal boosters, when the Daleks on Keska logged in at full strength, he essentially gave them concussions, leaving them immobile and vulnerable. (AUDIO: The Heart of the Battle)

As a result of the Last Great Time War changing timelines, the five original members of the New Dalek Paradigm had no way to verify the Pathweb's data of the conflict, discarding most of it as a result and choosing to distance their new state from the Dalek Empire. When the Paradigm's leadership reformed into the Parliament of the Daleks, only snippets of the body's discussion were uploaded to the Pathweb. (PROSE: Dalek: The Astounding Untold History of the Greatest Enemies of the Universe)

The Doctor once attempted to hack into the Pathweb, but was unsuccessful. When several inmates of the Dalek Asylum attacked his eleventh incarnation upon recognising him, Oswin Oswald, already part of the Pathweb because of her conversion into a Dalek, deleted all information connected with the Doctor from the Pathweb. This resulted in all memory of the Doctor by the Dalek race being forgotten. (TV: Asylum of the Daleks) Despite Oswin's efforts, the Daleks regained knowledge of the Doctor from Tasha Lem during the Siege of Trenzalore. (TV: The Time of the Doctor) The sudden remembrance of their foe drove the Prime Minister of the Daleks mad. (PROSE: Dalek: The Astounding Untold History of the Greatest Enemies of the Universe)

A Dalek christened Rusty by the Twelfth Doctor later had its suppressed memories unlocked and then saw several past Dalek experiences through the Pathweb (TV: Into the Dalek), which were the memories of Henry Van Statten's "Metaltron" exterminating Bywater as it escaped the Vault in the Battle of GeoComTex (TV: Dalek) and Davros's New Dalek Empire attacking the Valiant during the 21st century Dalek invasion of Earth. (TV: The Stolen Earth)

The Twelfth Doctor believed the hive mind's database was greater than even the Matrix on Gallifrey. With the help of Rusty, he accessed it to gain information on the Testament. Rusty was able to display the information he accessed holographically for the Doctor. (TV: Twice Upon a Time)
