The Microsoft corporate Web site, Microsoft.com, is one of the largest and most heavily visited sites on the Internet, yet it maintains consistently high availability ratings.

The Microsoft.com Operations (MSCOM Ops) team that operates the site meets these demands through a combination of carefully planned infrastructure; collaboration with other teams; and use of technology for maintenance, monitoring, and change management.

During the past eight years, Microsoft.com has achieved one of the highest rankings on the Internet in terms of site availability as measured by Keynote Systems Inc., an independent third party.

According to the Keynote reports, Microsoft.com has been available more than 99.8 percent of the time for the past five consecutive years, and more than 99.9 percent of the time for the past two years. The site generates more than 1.2 billion hits per day from more than 57 million unique Internet Protocol (IP) addresses.

This traffic generates 200 million daily page views, averages 30,000 Hypertext Transfer Protocol (HTTP) requests per second, and results in an average of 750,000 concurrent client connections.
