Microsoft.com Web site statistics
When www.microsoft.com started in 1994, the entire site was hosted on a single server that handled about a million hits a day. As the Internet expanded, more and more groups at Microsoft began adding content to the Web site. Today, more than 500 writers and developers working in more than 70 locations around the world provide information for the Microsoft Web site. Three data centers manage our online traffic. Within those data centers, 60 servers host general Web content, 11 servers host SQL, 50 servers respond to site searches, 49 servers handle download requests (along with thousands of global caching servers), and 10 servers host FTP content.
