Air Force network lockouts hit troops and civilians

Air Force employees are being locked out of their computers as cybersecurity quarantines tied to software updates disrupt work across bases and the Pentagon.

The Air Force is scrambling to get employees across the service back online after weeks of rolling cybersecurity quarantines locked numerous troops and civilians out of their computers, sometimes for days.

A quarantine kicks in to protect military networks from cyberattacks if a computer isn’t routinely updated with new software patches. But as the Air Force pushes out patches more often to stay ahead of digital threats, employees must make sure those updates are in place — or find their device rendered unusable.

The lockouts have created headaches at multiple bases and the Pentagon as the service continues rolling out forcewide software updates.

While quarantines aren’t new, the scale of the ongoing issue is unusual. The outage allegedly hit tens of thousands of devices, according to an anonymous post on “Air Force amn/nco/snco,” an unofficial Facebook page popular with airmen.

The Department of the Air Force declined to answer how many computers were affected or how long it could take to return them all to working condition, citing operational security.

“We are conducting routine updates to network security baselines to ensure the safety, security, and integrity of our systems against an evolving global threat landscape,” a department spokesperson told Federal News Network Tuesday. “Enforcement will continue as part [of] standard network maintenance and compliance efforts.”

For some, the interruptions are inconvenient but quickly remedied. For others, they can complicate travel plans, disrupt classrooms and slow missions.

Though some Facebook commenters said they were notified of a potential quarantine in advance, others said their computers locked down without warning. In some cases, people who thought they were in the clear still found their computers inaccessible. It’s unclear whether prior notice was given to everyone affected or if some in quarantine missed the memo.

Users are supposed to see a pop-up that asks them to choose between installing updates immediately or at a later time. Computers can also be manually updated without prompting. Employees are encouraged to restart their computers daily to make sure patches go through.

But if a computer isn’t updated quickly enough, or if it hasn’t recently connected to the network, it’s tagged as a security threat and quarantined. Then an employee has to visit their local communications squadron or similar technical experts to regain access, though that can take hours to days depending on how busy the office is.

“Attention: This workstation has been quarantined by 561,” read one laptop in a photo posted to Facebook, referring to the Air Force’s 561st Network Operations Squadron at Peterson Space Force Base, Colorado. “Non-compliance with one or more Comply to Connect rules. User access is restricted pending further analysis and remediation.”

The squadron is one of five that run the Cyberspace Security and Control System (CSCS), a centralized tool used to monitor traffic and block suspicious software on the Air Force’s portion of unclassified and classified Defense Department networks.

Comply-to-Connect is a DoD-wide program designed to identify and report all devices connected to military networks. The DoD inspector general’s office announced an audit of the program’s implementation in January 2025.

Though the Comply-to-Connect framework launched in 2013, military leaders have warned of the need for cyber hygiene — and quarantines — for decades.

“The Air Force cannot allow a weak link at one base to put the rest of the Air Force or DoD at risk. In fact, they could be forced to quarantine an entire base,” South Carolina’s Shaw Air Force Base warned in a 2009 release. “The mission impact would be significant from such an action.”
