WP1454v2: GOV.UK Broken link checking tool. Reissue WP1454 amended.

Tender description

Why the Work is Being Done GOV.UK must be a trusted source for users. Their safety, security and privacy must be protected while using the site. Problem to Be Solved Links to other sites on GOV.UK may break or the destination domains may be hijacked by malicious actors. Consequently malicious actors have the potential to direct users to expose private information. Content staff and publishers need to be able to monitor these links and fix them if they break.The work is expected to take no longer than 8 weeks. The milestone deliverables are: Integrate with daily feed from GOV.UK site crawler, Integrate with feed of changed content, Discovery and implementation of additional link checks, Record results of tests, Display results of tests, Set up automated reporting of results of tests Who Are the Users As a citizen I need to be able to trust links I click on GOV.UK so that I'm not tricked into disclosing my information to attackers Early Market Engagement None Work Already Done GOV.UK has a Link Checker API that accepts a URL and checks that it doesn't 404. It has been integrated with our Local Links Manager application which staff from local authorities use to update links from GOV.UK to services on their sites. GOV.UK has two RabbitMQ-based feeds of content which could be used to drive the checker. One is a nightly crawler which detects URLs on each page. The other is a live feed of newly published content. Existing Team The team that built the Alpha API and integrated it with Local Links Manager will be available to provide context and assist with code reviews. The work will be coordinated by a Delivery Manager and overseen by a Senior Technologist and Product Manager from GOV.UK. Once familiar with the work, the supplier is encouraged to work remotely.
