Rogers, one of the big three Canadian carriers, and its budget-branded subsidiary, Fido, are experiencing severe, nationwide voice network outages at the moment. Several of us here at iMore can't place calls at all, though data still works fine. It's supposedly coming back up, but we've not seen it yet. As you can imagine, Canadians depending on their cell phone service are in a bit of a panic. Albeit with traditional politeness.
If you're having a problem with your Rogers or Fido service, let us know where, and for how long you've been experiencing it. If it comes back, let us know same.
