I wouldn't get excited just yet. The whois record form amiga.com states that the domain expires in June 2011. So I suspect that this is most likely a temporary problem with the hosting provider rather than them failing to maintain their hosting.
Pinging amiga.com results in inconsistent replies for me:
PING amiga.org (174.120.31.90): 56 data bytes
64 bytes from 174.120.31.90: icmp_seq=0 ttl=47 time=153.263 ms

^C
so I suspect this is a routing issue or maybe even somebody carrying out a DDOS.
