Facebook not reading my OpenGraph on some pages

Question

I own a Facebook page here:

facebook.com/moonward

And everytime I post a new article on my blog I paste the url in the status and it usually picks up the OpenGraph correctly, but sometimes with some urls it fails horribly.

For example, this doesn't work:

http://www.moonward.net/inspiracion/2012/01/guy-laramee-esculturas-de-libros/

And this one does:

http://www.moonward.net/animacion/2011/12/diablo-iii-impresionante-video-introduccion-y-arte/

What's the difference? Why is this happening?

Answer 1

It seems the blogging engine or the hosting of that blog is very slow to respond.

Facebook's linter cannot get a response in a timely manner and give up.

Scrape Information Error Parsing URL: Error parsing input URL, no data was scraped.

Try for yourself:

EDIT

There are so many things that can cause the interwebs to be slow. Let's start at the content and list some of the points where the process can be slow. Remember, it may even be a combination of these issues, it doesn't have to be just one.

• The db is slow in returning data to the blog engine.
• The connection between the db and server is overloaded
• The blog engine is overloaded and cannot process the response/request from the db
• The blog engine is slow parsing that data to present as HTML
• the web server is slow sending out the HTML to the client
• the network between the webserver and firewall is overloaded
• the firewall is overloaded
• the interwebs are overloaded at some point in the tracert between the user and webserver.
