Yes, huge DNS issue with Videotron, but it should be back in Montréal since 16.30. Where are you from? If it's not working yet you can try to change the DNS from your device as shown in other questions

Yeah Videotron have some issues right know! Be patient abd stay around for more updates!
Good luck!

For a short term solution, you can change the DNS on your device or the Fizz modem.

For device, go to settings:
Obtain DNS: Manual (instead of automatic)
DNS1: 8.8.8.8
DNS2: 8.8.4.4
.
For Fizz modem, go to http://192.168.0.1/ (username: cusadmin and your wifi password)
Make this change for now and your internet will work.
