BOSTON (CBS) — Tufts Medical Center and Beth Israel Deaconess Medical Center were unable to receive calls from outside the respective hospitals.

The outages, which began late Sunday night, were due to a flood at Windstream Communications located on Congress Street, which supplies the phone system at both hospitals.

The hospitals asked anyone to get in touch with a patient to call their cell phone.

Both hospitals set up an alternative phone line for patients’ family members.

The issue was resolved late Monday afternoon.
