Conclusion

The quote from the Irresponsible Internet Statistics says it all:

Anamorph: The problem is this: there is no absolute way to measure any statistic regarding the growth of the Internet. As John Quarterman of MIDS says:

The Internet is distributed by nature. This is its strongest feature, since no single entity is in control, and its pieces run themselves, cooperating to form the network of networks that is the Internet. However, because no single entity is control, nobody knows everything about the Internet. Measuring it is especially hard because some parts choose to limit access to themselves to various degrees. So, instead of measurement, we have various forms of surveying and estimation.

So all the statistics presented here are based on estimates and conjecture. And even if they were absolutely true, growth rates change ... that there is only one conclusion that can possibly be drawn from such vague data:

The Internet is getting big, and it's happening fast.
