Here’s the notice on the wiki:
EVE University is refocusing their efforts on teaching players how to create a ship fitting to meet their needs, rather than providing fittings that are often used as-is, without communicating an understanding for why the fitting was created in that manner.
As a result, The UniWiki will soon be removing its repository of ship fittings. They will be replaced with a renewed focus on ship-specific roles and bonuses, as well as links to broader articles on how to fit ships for those roles and bonuses. UniWiki will also provide links to other websites (e.g. zKillboard, EveWorkbench) and articles on how to find suitable fits on those websites.
This notice is to provide you the opportunity to save your favorite fits. There is no set date for the Fittings removal, but it will likely occur within the first week of August, 2020. The process to remove fittings will be accomplished automatically, and does not require assistance or editing by wiki contributors. Thank you – EVE University / UniWiki Management
