input: [Status] Partial [Fetch and Render] Google got a response from your site and fetched URL, but we could not reach some of the resources on that URL for rendering. [Notes & Next Steps] 
output: You can assess the gravity of the situation by clicking through the missing resources. A fetch with the Partial status could mean a small problem with the page (e.g. few or insignificant resources could not be retrieved) or a more serious one (e.g. many or important resources which include a large part of the page content are missing). Note that occasionally, blocked resources reside on other domains, which you might not be able to control. If important page content is missing due a blocked resource on another site, you might want to contact the resource owner to allow Google to access that resource. It is also possible that the rendered URL references some resources that simply do not exist.
