An outage with AT&T has prevented wireless customers from making 911 emergency calls for nearly two hours Wednesday night.

The outage affected customers' cell phones nationwide. The issue has now been resolved and AT&T has issued out the following statement via Twitter:

According to the Plant City Police Department, the emergency 911 system may not be currently working for AT&T users in the area and customers are being urged to use the non-emergency number instead: (813) 757-9200.

Karen McAllister, senior relations manager for AT&T for West Florida, also issued a statement for the locally affected areas:

Service has been restored for wireless customers affected by an issue connecting to 911. We apologize to those affected.

Agencies throughout Texas, Florida, Tennessee and Washington, D.C, sent out tweets saying they've been affected by the outage and provided different numbers for the public to call instead.
