IANA's email about why example.com changed

IANA's VP, Kim Davies, explains by email that the recent changes to example.com were driven by practical concerns: the site is heavily trafficked and exists primarily as a placeholder for use in documentation and examples, not as a general-purpose endpoint. To reduce bandwidth and maintain utility, the visible content was split into a minimal HTML page with supplemental content delivered via a separate JavaScript file. Because much of the traffic is automated and does not fetch the JavaScript, this structure lowers overall data transfer while preserving informative material for human visitors.

Davies clarifies that the domain’s purpose is illustrative - for copy-pasted sample configurations and documentation - and not intended for availability testing or other operational uses, so running an HTTP service is a courtesy rather than a requirement. The message emphasizes that changes are made to balance bandwidth demands and usefulness, notes that the site historically informed visitors about the domain’s intended use, and invites further questions. The email also grants permission to reuse and circulate the explanation.
