If you received a message saying that a page was eaten, then the page could not be found on our server. Double-check the URL and try loading the page again, just in case the server was briefly unavailable. If that fails, then the page was likely moved or deleted. Unless the page in question is a top-level page, we cannot help you, as we only maintain the top-level pages. If you have questions, try mailing the former contact address of that particular page. If the URL is of the form http://www.mit.edu/people/username, then mail that username@mit.edu.
