People using cellular telephones to reach Fort Wayne or Allen County Communications’ 911 service need to use an alternate number until further notice, police said shortly after 5:20 p.m. Wednesday.
 Land lines are unaffected by this outage, the city said.
Cell phone users should call 427-1222 to reach the city or 449-3000 to reach the county.
The problem is expected to be resolved later this evening, the city said.
Indigital Telecom identified an equipment failure in the Indiana Fiber Network’s 911 system for cellular calls and is working to resolve the problem.
The city said media will be updated when service is restored.
