Let’s be abundantly clear: as of this writing, there’s still no official word on what caused the Verizon outage. The FCC has launched an investigation, but Verizon has remained mostly silent, offering only a brief apology acknowledging the disruption and stating that the issue is being resolved.

Verizon has confirmed that its cell service is beginning to come back online following a massive outage affecting some of its mobile phone customers.

Verizon confirmed an outage on its X social media account just before 9 a.m. It wasn’t until 2 p.m. that it announced it was making progress in addressing in the issue and said some service was being restored. The issue affected voice, data and text services.
