Whelp, if you were looking to play your favorite Ubisoft game today, you may be out of luck, at least for the time being. Ubisoft Support just tweeted out that the company is experiencing a DDoS attack, and it is impacting the connectivity of multiple games across all platforms, inducing the just released Assassin's Creed Odyssey.
This appears to have been going on for a few hours now and there doesn't appear to be ending anytime soon. We will keep you posted with any updates that get sent out.
[UPDATE: DAN] The DDoS has been resolved, but there are still some connectivity issues being experienced by users.
