can I cancel a 301 or 410 redirect?
 

What I would do, when canceling a redirect, is a Fetch and Render from Google Search Console to that URL and then submit to index, so Google knows that that URL now has content again. Otherwise, it can take months or even years for Google to come back to that URL, because it assumes you’ve redirected or deleted it. So use Fetch and Render for that and get those old URLs back in if you really need to. If you need to do this a lot, you need to think about your redirection strategy and whether you’re redirecting too quickly though
