The Federal Communications Commission has alerted broadcasters to a disruption of its Universal Licensing System (ULS). Various services have been unavailable since Friday, June 9.

Affected systems include the commission’s Tower Construction Notification System (TCNS), E-106 System and Antenna Structure Registration System (ASR). The FCC says this disruption is due to technical issues. During this time, no applications may be filed through the database.

As of June 13, there is no timeline for recovery, although the commission says it anticipates resolving these problems
