If you're on Rogers, you may well wait longer than you think - they 
will detect such and shut down service to you. (-:

[Or, at least, this is my best guess / understanding of 3 different 
Rogers service shutdowns, of 3 different people, over the last few 
years. Only once was I able to get to a tech who confirmed that was 
the cause of the shutdown. Course, this was found out a week later, by 
which time the cause had been automatically cleaned, and I had spent 
many, many, hours looking for a problem that no longer existed.]
