It's a bit of a confirmation, but according to netstat:

tcp        0      0 satan:www               ny-131.algorithmi:13082 SYN_RECV

SYN_RECV means a request has been received from the network.  This
proves that the http request was received at the right machine, at the
right port.  But for whatever reason, the connection was never fully
established.  I'm not sure if this is telling me there's a problem
with the TCP transport or if this is simply restating the fact that
Apache isn't picking up the phone.
