Megalodon (Japanese: ウェブ魚拓, "web gyotaku") is an on demand web citation service based in Japan.[2] It is owned by Affility.
Megalodon's server can be searched for "web gyotaku" or copies of web pages, by prefixing any URL with "gyo.tc"; the process checks the query against other services as well, including Google's cached pages and Mementos.[3]
On 12 November 2010, Affility revealed that all files copied before the first half of 2007 were lost because of a malfunction in their backup process.[citation needed]
Megalodon does not archive sites which include a "noindex" or "noarchive" tag in the robots.txt file.[4]
