The Anne Arundel County government is investigating a “cyber incident” that began disrupting county services Saturday, according to a post from the county on the social media platform X.

At 10:15 a.m. Saturday, the county’s government posted that some of its public services were down but that both 911 and 311 remained operational. In an update posted around 5 p.m., the county identified that its Office of Information Technology, public safety officials and cybersecurity experts were working to investigate an “ongoing cyber incident of external origin” that was affecting county services.

County officials said they are taking a “proactive approach” to ensure the systems are safe. A post on X from the county government noted that precautionary measures included limiting access to the internet until the county government is able to return to full operations.

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

The county did not respond to question of which services were impacted and whether this could be considered a cyberattack.

Sunday evening, some services on the county’s website, like the portal for paying water and utility bills, had long load times and eventually sent “server error” and “runtime error” messages to users.
