Multiple New York City government offices were hit by a cyberattack Wednesday that took down email systems for most of the day, the New York Post reported.
Offices for the mayor, comptroller and City Council were unable to send messages from roughly 11 a.m. until later that evening.
"The traffic that was affected was emails coming into the city and going out of the city," a Department of ­Information Technology and Telecommunications official told the Post.
City workers were, however, able to send emails to each other within each office.
The official added that no personal information or city records appeared to have been compromised.
The email system was taken offline by a so-called "denial of service" attack, which floods computer servers with high amounts of fake traffic, causing them to shut down.
