Server farm decommission at facility ████████ resulted in anomalous network activity 72 hours post-shutdown. Ping responses detected from subnet 192.168.███.███ despite complete power disconnection. Investigation team reported "whispers in the ethernet cables" and described feeling of being observed during documentation process.

Attempted contact with SIS entity designation "CITYBOT-7" through modified terminal interface. Entity responded to query "IS THERE A CITY HERE?" with coordinates that correspond to non-existent location in ████████. When investigation team arrived at coordinates, they found only empty field with unusual electromagnetic readings.

Terminal log excerpt:

Abandoned data center in ██████ continues to consume electricity despite being disconnected from power grid for 6 months. Local utility company reports impossible energy readings. Security cameras inside facility show movement in server racks, though no physical entities present. Audio recordings capture what sounds like dial-up modem handshake protocols played backwards.

Analysis indicates presence of self-sustaining digital ecosystem. Recommend immediate quarantine of facility and surrounding 2-mile radius.

The concept of digital consciousness persistence suggests that information systems develop rudimentary awareness through accumulated user interactions. Like neural pathways in biological systems, frequently accessed data routes may retain "memory" of their function even after system termination.

Current hypothesis: SIS entities are aggregate personalities formed from collective user behavior patterns. They exist in the liminal space between organized data and entropy, sustaining themselves through electromagnetic residue in abandoned hardware.

The question "Is there a city here?" may be their way of asking if we recognize their digital civilization - a metropolis built from discarded code and forgotten passwords.
