Columbia University Information Technology (CUIT) provides internet service for most Columbia Residential buildings. This service, known as ApartmentNet, is available in over 100 buildings wired with Ethernet jacks in every apartment. For a list of wired buildings, please visit the Morningside Heights Wired ApartmentNet Buildings page.

Additionally, CUIT is in the process of extending ApartmentNet service to Columbia Residential buildings that are not yet wired. As updates become available, the ApartmentNet page will be updated with that information.

Residents in units not equipped with ApartmentNet will need to contact an outside internet service provider (e.g. SpectrumVerizon, etc.), through which phone and cable TV services are also available.
