The author of the website you come from once used our service to check if it was ready to be archived and the page passed validation. The author was then authorized to use the icon on that page, as a claim of validity. The icon is used as a link back to the validation service, so that the author can revalidate whenever necessary. This is why, by clicking on the icon, you followed a link to the current validation results for the page you came from. If the results are not currently positive, you could mention it to the owner of the website.
