CMS students face internet connectivity issues at home due to a statewide security software problem.

CHARLOTTE, N.C. — Charlotte-Mecklenburg Schools students are experiencing difficulty connecting to the internet from home using their school-issued devices due to a statewide problem with the district’s security filtering system.

The district notified families on Tuesday that issues with Zscaler, the security software that filters internet content on CMS devices, are preventing students from accessing online resources when their devices are used outside the school network.

The connectivity problems come as students increasingly rely on district-provided technology for homework, research, and educational activities at home. The district has not specified how many students are affected by the outage.

“Our team is working closely with the vendor to resolve this issue as quickly as possible,” the district said in a message to families. “We understand how important reliable access is for students and families.”

The district characterized the problem as affecting the entire state, though it was unclear Tuesday whether other North Carolina school systems using similar filtering software were experiencing the same issues.

CMS officials said they would provide updates once the connectivity problems are resolved. The district did not provide a timeline for when normal internet access might be restored to the affected devices.
