title: Why Flickr api working for only some amount of time
body: <p>I am trying to access <strong>public feed</strong> via
  <a href="https://api.flickr.com/services/feeds/photos_public.gne" rel="nofollow noreferrer">https://api.flickr.com/services/feeds/photos_public.gne</a>
  which I get from
  <a href="https://www.flickr.com/services/feeds/docs/photos_public/" rel="nofollow noreferrer">https://www.flickr.com/services/feeds/docs/photos_public/</a>
  but It says "<strong>Flickr API:Page not found</strong>"
  so how to proceed?
  (note:<strong>api works sometimes!</strong>)</p>
