Verizon experienced a significant network outage that left thousands of customers without service across multiple states, including California, Michigan, and Chicago. As users reported their phones being limited to SOS mode, the carrier confirmed that it was aware of the disruptions impacting mobile services. Following a day of issues, Verizon announced that service has been restored and is now operating at normal levels. The Federal Communications Commission (FCC) has initiated an investigation into the outage, which affected over 100,000 customers. Despite the challenges, some users reported that emergency services and businesses in areas like the Bay Area continued to operate as usual during the outage.
