Link Checker Update — Feb 2024

Modified on: Mon, 29 Apr, 2024 at 3:39 PM

What’s changing

We’re modernizing our link checker, which scans for broken links. This modernization will increase the efficiency and scalability of our link checking capabilities. 

What does this mean?

The improved architecture of the new link checker will allow us to handle more customer sites simultaneously. It adopts a more restrained approach when scrutinizing domains for links, reducing the likelihood of false positives over time. While the transition to the new link checker may not yield immediate changes, its enhanced capabilities promise improved accuracy and efficiency.
You should not see an impact on your DCI score with this update.

When is this happening?

The migration to the new link checker will be rolled out in a phased approach between May and October 2024. 

Customers will receive further communication one month ahead of their scheduled migration date.

An annotation in the graphs within Quality Assurance, Accessibility, SEO, and Policy will be added once the migration has happened. This annotation will indicate the specific migration date of the site.

How do I report any new issues?

We do not anticipate any interruptions or visible impact from this update. However, if you encounter an issue that you believe to be related to this change, please get in touch with our support team by emailing
