In accordance with our Sourcing policy, all links to external sites must include a link to a backup version, preferably using Internet Archive. Instances that do not include one of the following parameters will result in the page being placed in the maintenance category.
|archivedate=20200324214406 This parameter uses the timestamp feature of Internet Archive. The URL supplied earlier in the template, along with archivedate, will provide a link to Internet Archive.
|archiveurl=https://archive.is/EfD8P If Internet Archive does not work for the link in question, you can use archiveurl to provide a full URL to another backup website, such as archive.is.
|nobackup=1 If no backup link can be found for content that is no longer available, this parameter can be used. If the content is still available, you can screenshot and upload it to Wookieepedia instead.
