“Federal government websites were hit by a cyberattack Wednesday and the hacking group Anonymous has claimed responsibility for the attack.
The websites for several federal departments — including Weather.gc.ca, ServiceCanada.gc.ca and Parl.gc.ca — went down around the lunch hour ET Wednesday.
Many federal employees also lost email service. Some sites, such as National Defence, remained online.”
