Re: Google vulnerabilities with PoC

I suggest you to read on Content Delivery Network Architectures .

 YouTube.com populates and distributes stored files to multiple servers
through a CDN (Content Delivery Architecture), where each video uses more
than one machine (hosted by a cluster). Less populated video files are
normally stored in various colocation sites. The YouTube architecture uses
databases for storing metadata information of all uploaded files.
