Stanford is currently experiencing a service disruption with approximately 10% of its telephone infrastructure. This impacts phone services at student dormitories and a subset of campus telephones, elevator lines, and fax lines. If you do not receive a dial tone when attempting to use a phone or fax line, it is affected by the service disruption and you cannot use it to place or receive calls/faxes. Additionally, some alarm circuits may not function normally.
Affected phones and circuits are found in locations throughout the university.
Most phone services — including all Voice over IP (VoIP) service and campus cell phone coverage — continue to work normally.
If you are impacted by this service disruption and need to place an emergency call (i.e., 911), you should use another phone, cell phone, or an emergency blue tower phone.
University IT is working to isolate and correct the issue and will provide updates here.
