As I type this it appears that Rogers along with their Fido brand is down for many Canadians. This is confirmed by DownDetector here:
And here:
This was further confirmed via this Reddit thread. The core issue appears to be DNS which seems to be an ongoing issue for Rogers as they have had issues with their DNS servers in the last few months leading to a similar outage. Users on Reddit say that changing your DNS from the Rogers one to say Cloudflare or Google can get you back online. Thus if you want a quick workaround, that would be it.
From what I can tell, Rogers has yet to admit that there is a problem. But plenty of their customers have noticed it:
And the timing of this outage could not have been worse for Rogers as they are set to increase prices. Perhaps they should focus on increasing reliability first? Just a thought.
More info as it comes.
UPDATE: According to this Reddit thread service is starting to come back online. But I suspect that a non-trivial amount of users will be dialing up Bell to move their services over to them in the morning because based on the rage that I am seeing on both Twitter and Reddit, Rogers really has managed to anger a whole lot of people with this outage.
