Problems with card access system

Last week on Monday, many doors, such as those in the Stata center, did not automatically unlock at their scheduled times. The problem was a database failure in the system that controls doors across campus, according to Thomas W. Komola, a project manager in the Security and Emergency Management Office.

The root cause of the problem remains unclear.

Komola said the problem began around 5 a.m. Monday, Feb. 8, and was resolved about 21 hours later, or 1 a.m. Tuesday. In addition to keeping doors from unlocking as scheduled, the database failure prevented anyone from adding new data to the system.

Komola said that the system failure did not unlock any previously-locked doors. The system is called CCURE (pronounced “secure”).

The security office plans to deploy a second instance of the database to increase reliability, Komola said.
