There are more than half a billion websites on the Internet.

In October, there were more than half a billion websites on the internet, or 504.8 million. This is 3.8% more than in September 2011. Thus, the number of web resources exceeded the half-billion mark for the first time.

These data are presented in a report by the research company Netcraft.

The company also reports that all software web servers that power websites have increased their user base.

In particular, the Apache web server, the market leader in web server software, increased its database of served websites by 10 million. The popular Nginx server increased its database of served hosts by 4 million units, now controlling 8.5% of the global market.

Apache's market share decreased by 1.09% over the month, with Nginx showing the most rapid growth.
