Google redid their removal tool in Google Search Console in 2020 but the tool has generally always been quick. John Mueller of Google said in the past that it takes less than a day and that it is very quick. So one person tested it and said it took only two hours!
I asked one SEO on Twitter who asked John Mueller the other day how long it takes, to tell me how long it actually took. The person said "it took like 2 hours from when I was clicking "cancel request" until the URLs were live in Google again."
That is quick!
Update: it took like 2 hours from when I was clicking "cancel request" until the URL:s was live in Googles products again. And I was "asking" about that removal for those URLs like 4 days ago.
