UAS Mosaic Silktide guidance

Silktide is the web platform available for use by UAS sections, to check websites for accuracy - for example, spelling mistakes and broken links - and to ensure that accessibility standards are achieved.

It is the responsibility of a site's editors to ensure that their site is accurate and that the content meets accessibility standards to comply with current legislation. Some issues of accessibility are dealt with at 'a platform level', and some issues which may be reported by Silktide, but are beyond the scope of the editor to fix, are listed in the guidance documents.

Lead editors are given access to check the reporting for their sites as standards. If other users need to be added they should be requested to, and these will be considered on a case-by-case basis.

Users can receive an automated email from Silktide with a report giving issues found on their site. This can be sent after every 'crawl', which is usually every five days, or monthly. To ask for this to be set up, email

Crawls of the site to check for issues occur as standard every five days. If an intermediate crawl is required, this can be requested by email to, however, note that crawls are a lengthy process, and new results may not be seen until the following day. 


If your website is not part of the UAS collection, but you are interested in using Silktide, please contact for more information.
