Wireless carrier T-Mobile on Monday suffered a major outage in the United States that impacted service at other carriers as well, and it ended up being reported as a "Massive" distributed denial of service attack.

Because some of these accounts contained account information for T-Mobile customers and employees, the attack essentially resulted in that data being accessed by a third-party.
