About this network

The municipal network of the City of Pasadena, California, operating under the handle PASADENA-ASN.

What it's used for

• City government networking: municipal offices, public safety, libraries, and traffic and utility operations riding the city's own fiber plant.

Notable

• A local-government network, not a commercial ISP. Addresses here belong to city staff and city systems.
• Pasadena runs its own municipal fiber network, built out from the mid-1990s when Pasadena Water and Power needed better links between substations than its aging copper lines. The city now operates roughly 50 miles of fiber.

Interesting

• Beyond serving city facilities, Pasadena leases dark fiber and sells lit services to local institutions, a customer list that has included Caltech, ArtCenter College of Design, and NASA's Jet Propulsion Laboratory.
