LTE service on Rogers seems to be back up again at least in some areas.
I just noticed that Rogers LTE service is down as my iPhone 5 is defaulting to 3G. A quick call to Rogers Technical Support confirmed there is a problem with LTE and Rogers One Number. I guess we will have to survive with good old 3G for a while. No word yet on whether this is related to the data overcharges that some Rogers customers have been reporting.
