Montreal public health made the announcement Tuesday afternoon on social media, saying its website is also down.

“We apologize for any inconvenience,” the websites read. “We are working diligently to bring back the sites as soon as possible.”

Jocelyne Boudreau, who works at the CIUSSS de Centre-Sud-de-l’Île-de Montréal, said the attack specifically targetted the company that hosts the health boards’ websites. She said that the outage dates back to Nov. 29, but could not provide more details.
