AFAIR, Netcraft says that it was broken somewhere in 2.5, and it began to wrap again. Moreover, it would be great if you could tell method how Netcraft is determining uptime remotely - they changed counters to 64bit, and what?.. Where it is in TCP/IP stack?

Not equally. Are the BSD machines in Top 50 really vulnerable to remote code execution attacks?..
