The Internet Backbone is beginning to already show struggles of all the new high data Internet services and we've been informed by experts in the past that we would expect brown outs by 2010 (now only 1.75 years away).

Bharti Airtel, Global Transit, Google, KDDI Corporation, Pacnet and SingTel are planning to build a new trans-Pacific cable between Japan and California and will initially increase Trans–Pacific lit cable capacity by about 20 percent, with the potential to add up to 7.68 Terabits per second.

Google's approach isn't the answer to this issue but it is indeed a stepping stone to ensure we won't experience Internet dropouts into the future.

“[Google’s] participation in building Unity ultimately helps provide our users with faster and more reliable connectivity.

If you’re wondering whether [Google is] going into the undersea cable business, the answer is no. We’re not competing with telecom providers, but the volume of data we need to move around the world has grown to the point where in some cases we’ve exceeded the ability traditional players can offer. Our partnership with these companies is just another step in ensuring that we’re delivering the best possible experience to people around the world.” Google’s Manager of Network Acquisitions, Francois Sterin
