I see no sign of my usage bottling up the internet.
From everything I've ever read, yes in fact it can bottleneck connections in busier areas on DSL for example.
Downloading server files every night is not a 'standard' thing that most people do. It is, for the most part, a faculty of business.
Businesses pay expenses. Most IPS's have premium business services which offer most bandwidth. Both major providers where I live do.
The average person browsing the average amount of time online not downloading backups of their website every night won't even understand, or be affected by this in my opinion. :)
