Based on Credit Suisse's bandwidth cost estimate, it seems like YouTube would have to be pushing more than 10PB per day (petabytes). That's assuming a $0.10/GB bandwidth cost. Now, I'm sure that Google is getting a lower bandwidth cost than I can get on a dedicated server as just me with my credit card.<p>So, I think it's safe to assume from those numbers that Google's pushing a few dozen petabytes from YouTube every day. That's a lot of data.
