question in draft-ietf-ngtrans-harden-01.txt

[kay ($B%N%0%A%1%$(B)]

Hi, folks

I have one question in draft-ietf-ngtrans-harden-01.txt.
In Section 7.1, b, draft says

        appropriate hierarchy.  This includes a high uptime 
        availability of the site router (greater than 99%). This

What does this "99%" digit mean?

     1) availability of bgp peering with neighbours?
     2) availability of router machine itself?
     3) or something else?

Thanks in advance
