Anne Arundel County government buildings will reopen with some disruptions Tuesday following a “cyber incident” that began Saturday and ended Monday, County Executive Steuart Pittman said in a news release.

Non-emergency county employees are being encouraged to work from home and residents should call individual departments to make sure they are open before visiting.

Emergency and essential employees must report for work at their usual times in consultation with their supervisors.

County officials do not have a timeline for when full service will be restored but said they would provide updates via social media.

The cyber incident did not affect Anne Arundel County Public Schools or Anne Arundel County Public Library, which operated normally Monday. All Department of Recreation and Parks amenities, including regional parks, also were open.

“As Anne Arundel County continues to respond to an ongoing cyber incident of external origins, I want to thank our residents for their patience as certain county services remain offline temporarily,” Pittman wrote on X Monday.

Pittman’s office declined to comment throughout the day on the exact services and departments out of commission.

Throughout Monday, government sites warned that due to an ongoing cyber incident, county buildings would be closed.

In a Sunday release, emergency and essential employees were asked to report to work as usual while other, nonemergency workers were advised to work remotely, if possible.

The incident began Saturday when the county government posted that some of its public services were down but both 911 and 311 were working.

The county later said its Office of Information Technology, public safety officials and cybersecurity experts were working to investigate the cyber threat. The FBI did not respond to a request for comment on whether the bureau is involved in the investigation.
