AT&T is claiming the massive phone outage on February 23rd that affected millions of calls, including 911 calls, was not caused by a cyber attack at all. Rather, they said, “we believe that today’s outage was caused by the application and execution of an incorrect process used as we were expanding our network, not a cyber-attack. We are continuing our assessment of today’s outage to ensure we keep delivering the service that our customers deserve.”

“Based on our initial review, we believe that today’s outage was caused by the application and execution of an incorrect process used as we were expanding our network, not a cyber attack,” AT&T said in a statement published to its website.
“We are continuing our assessment of today’s outage to ensure we keep delivering the service that our customers deserve,” the statement concluded without going into more detail.
