Extract¶

The June 2001 Netcraft Web Server Survey received responses from 29,302,656 sites. Market share by hostname: Apache 63.02% (18,466,153 sites), Microsoft-IIS 20.38% (5,972,321 sites), Netscape-Enterprise 6.04% (1,768,673 sites), Zeus 2.76% (810,108 sites). Apache gained 0.78 percentage points from May to June 2001, while IIS declined 0.14 points. Active site breakdown: Apache 62.42% (7,346,025), Microsoft 26.14% (3,076,623), iPlanet 2.32% (273,293).

Relevance to Hypotheses¶

Hypothesis	Relationship	Strength
H1	Supports	Directly confirms Apache's 63% dominance by hostname count
H2	Contradicts	Even by active sites, Apache held 62% — not just inflated by parked domains
H3	Supports	Provides one half of the measurement duality (hostname perspective)

Context¶

The 29.3M sites surveyed represented the entire visible web at the time. The hostname metric was the standard industry metric for web server market share in 2001. Netscape-Enterprise at 6% was in clear decline, having been the second-largest server in the late 1990s.
