And the uptime means what?

My point is simple, we can head down an nonconstructive path of 
comparing "Apples" and "Oranges", or we can begin to understand and 
appreciate the complimentary nature of LD Fragments in regards to Linked 
Open Data deployment.

I say "Apples" vs "Oranges" because that's like trying to compare 
ODBC/JDBC API access and generic SQL access to a SQL RDBMS, in regards 
to some notion of "uptime" on a publicly accessible network. In fact, 
even that isn't quite accurate, in the context of the Web, but its the 
closest technical anecdote we have right now.

I can assure you that all is not what it seems in regards to what 
"uptime" means, and how it is achieved. Creating the illusion of 99.99% 
uptime isn't an issue here, but that's what I sense you are referring 
to, based on your recycling of fundamental misconceptions about this 
matter.
