Cleveland City Hall and government offices in the Erieview Plaza will remain closed Tuesday after a "cyber event" shuttered the halls of government Monday.
Officials were closed-lipped during a press conference Tuesday afternoon. Cleveland Mayor Justin Bibb said the city is working with a "multitude of partners" to investigate, but did not release details about the nature of the event or what systems were affected and how.
The city identified the "abnormality" Saturday, according to Kimberly Roy-Wilson Commissioner of the city's Division of Information Technology Services. Officials said they've been working to address it around the clock since.
In a press release issued Sunday evening, a city spokesperson said the "nature and scope" of the "cyber incident" are not yet known, but leaders decided to close City Hall and the affected systems as a "precautionary measure."
"We take cyber threats extremely seriously and are working expeditiously to rectify the situation as soon as possible," a city spokesperson wrote in a news release.
The spokesperson said all internal systems and software platforms will be shut down "until further notice," but no further information is available.
City and emergency services including public safety, city airports and public utilities are not affected, according to the city.
Residents may still contact 911, but all daytime 311 calls will be handled after hours as operations remain offline.
This is a developing story and will be updated.
