According to this link (after a few seconds of googling), Visa's network was down for 8 minutes in the five years ending 2001. Do you have citations for any of your claims? Edit: Oops, here's the link: http://www.forbes.com/global/2002/0916/038.html http://www.forbes.com/global/2002/0916/038.html

The Visa figure I heard at the Computer History Museum years ago, it was first decades so that may have changed. Goldman Sachs told me when I was writing a proposal for them years ago that they have over a petabyte of data stored. The web is 80-200TB depending on who you ask. A single department there responsible for the program based trading would alone have an entire copy of the web (and parts of the deep web, and all of twitter, etc.) since they construct those whack trading apps that suck everything up and analyze it for signals. If there are any quants on here they could tell you about this more. The airline system I was referring to is SABRE. Early IBM was built on their rollouts and we are talking about the 50s. V interesting story, lots of references from this page: http://en.wikipedia.org/wiki/Sabre_(computer_system)#History http://en.wikipedia.org/wiki/Sabre_(computer_system)#History

  The web is only 200TB? That seems wrong by orders of magnitude to me. Maybe you mean Google's publicly indexed web?

    well yes, indexed web - otherwise it would be all the data everywhere bar a few nuclear facilities.

  I think you're grossly underestimating the size of the Web. Flickr alone were storing 15TB of new photos a month back in 2006: http://blog.forret.com/2006/10/a-picture-a-day-flickrs-storage-growth/ http://blog.forret.com/2006/10/a-picture-a-day-flickrs-stora...

    it was 8 years ago - the numbers for both have undoubtably increased (it was ~10x the web at the time)

    sorry I just re-read my post, should have been past tense, i have been up for too long. It would be interesting to get more recent figures and compare again, because I do know that the investment banks hoard a lot of data. In terms of just documents, they would easily store more than the web

  One of my professors told me YouTube is hosting approximately 100TB of new videos every month, I think 200 TB is off by very, very much. If 200TB was the case I could afford to buy disks to store the entire web with my yearly salary...
