perlow tips his blog entry over at ZDNet on why the Internet didn't melt when millions of users streamed 480i video for a week. The short answer is Limelight Networks of Tempe, Arizona. "[W]hy the Internet didn't 'melt' is quite simple — [Limelight is] completely 'off the cloud.' In other words, unlike Akamai and similar content caching providers, their system isn't deployed over the public Internet... Limelight has partnered with over 800 broadband Internet providers worldwide... so that the content is either co-located in the same facility as your ISP's main communications infrastructure, or it leases a dedicated Optical Carrier line so that it actually appears as part of your ISP's internal network. In most cases, you're never even leaving your Tier 1 provider to get the video."
