2,500 continuous runtime hours on a 4.77Mhz DOS web server

"Dead" for me is if it actually crashed and does not recover without interference. I'm not surprised that an 8088 (not even an 8086!) will either take a really long time to reply SYNACK, or just drop packets entirely when the queue is full, when hammered with HN levels of crowds.

It may be dead, but it also may just be busy.

A few things to consider here:

  * It's getting hammered.  I didn't expect it to be this bad.
  * If it can't process things fast enough packets might be dropped.  So the TCP/IP error rates are probably pretty high right now.
  * It's logging all of this crap too ...

Normally it can do the handshake in tens of milliseconds. Right now the load on it is basically "crush." But it's queuing and answering as best as it can.
