As people spread beyond Golarion, so too did the Cloud Giants. Every world that could host clouds of any kind had some cloud castles containing their servers.The ones on Golarion became separated when it vanished, but the CloudWeb survived, full of posts, images, and stories with undeterminable degrees of accuracy. Since the Cloud servers are connected via the plane of air, most believe Golarion is separate from all elemental planes.
Data storage is in silicon atoms suspended in the actual clouds having the digital setting of either an extra electron or a normal charge. The servers contain the directories so specific files can be found. Such clouds glitter and are not part of the water cycle.
No planetary government acknowledges it or their use of it, but it's there that hackers trade conspiracy theories, the most universally popular Icons post their videos and sitcoms, and the best VR games spread.
The adventurers might be offered 20 thousand credits a head for the hackers spreading ransomware throughout the cloudweb.
