The City of Tulsa on Sunday said a number of municipal network services were being impacted by a ransomware attack.
"No customer information has been compromised, but residents will see delays in network services. The City’s Information Technology and security teams are working with a security advisor and have shut down many internal systems out of an abundance of caution," the city wrote on Facebook. The city's website was down as of 7:45 a.m. Monday.
"911 is operational and the City’s public safety response is continuing as normal," the city said, though 311, some credit card payment systems, and the city's new online utility billing system were impacted.
