October 2006 Web Server Survey

In the October 2006 survey we received responses from 97,932,447 sites, an increase of 1.08 million from last month. That moderate growth follows four straight months of blockbuster gains, guaranteeing that 2006 will surpass 2005 in the record books for largest single-year hostname growth. The survey has added nearly 23.9 million sites in the first 10 months of 2006, well above the previous record for annual numerical site growth of 17.1 million from last year. At its current 2006 growth rate of 2.3 million-plus sites per month, the Web Server Survey could top 100 million sites before the end of the year.

There are only small shifts in market share for web server software. Windows' share improves slightly this month, as gains at Go Daddy offset some slippage among sites hosted at Microsoft.
