MONTREAL — Quebec’s power utility says its website and mobile application have been knocked offline by a cyberattack.

Hydro-Québec says it was targeted at around 3 a.m. by a denial-of-service assault — when attackers flood an internet server with traffic and overwhelm it. 

The utility says the attack has shut down its website and cellphone application but says its critical systems are not affected. 

Hydro also says there was no data breach and personal data was not compromised.
