I think you're mistaken about the server being off-line, since I can  
see it just fine from many places. The RIPE NCC dnsmon tool can also  
see it from its various probes:

   http://dnsmon.ripe.net/dns-servmon/server/?server=h.gtld- 
servers.net&show=SHOW

I don't know any details about how that servers is deployed, however,  
so it's non-trivial to draw more conclusions about what problems  
you're having. Perhaps a single anycast node has some issues, or  
perhaps 192.54.112.0/24 has flapped a bit, and has been suppressed  
due to dampening in your neck of the woods.
