If you have more than 500 blog then change the 1 (after index=) to 501 (now it will look like thisatom.xml?redirect=false&start-index=501&max-results=500) then again copy-past and submit it
Now it will index your next 500 blog post, like this you have to do it
 Suppose you have 2000+ blog post then you need to submit each line one by one
atom.xml?redirect=false&start-index=1&max-results=500
atom.xml?redirect=false&start-index=501&max-results=500
atom.xml?redirect=false&start-index=1001&max-results=500
atom.xml?redirect=false&start-index=1501&max-results=500
atom.xml?redirect=false&start-index=2001&max-results=500

If your sitemap status change to green that means your sitemap is successfully submitted to Google for indexing, but if it get change to red instead of green then check the text whether you have copy-past or typed it correctly or not (there should be no blank SPACE). Even you can check it by typing anyone of those lines after your blog URL in your Web Browser address bar.
If you have any question or problem let me know.
