Statistics about the linked data cloud

Hi,

I am looking for statistics about the linked data cloud (datasets, their
domain, the number of in-links, etc.). There seem that there has been a
catalog that provide such information [1], but it is no longer available. I
will be grateful if you could point me to a source of information.

Regards,
khalid
