2003: Year of Apache
John Chamberlain writes "Netcraft's numbers for the new year are in. The trend graphs tell a story: 2003 was the Year of Apache. If Time magazine had a server-of-the-year award the cover would be featuring a feather. Since October 2002 market share has grown from 53% to 64%, a 20% gain while Microsoft IIS, its nearest competitor has shrunk from 36% to 24%, a 33% decline. The change in server totals was even more dramatic. Apache HTTP Server increased from about 20 million to 32 million (+60%) while all other competitors remained flat."
That was a switch from one of the big parking companies, IIRC. Thousands of domains all changed at once. It's one of those things that fits into the "how do we measure this" decision. If a website in the middle of the forest doesn't have an index, is it still counted?
