Though I do not really see an analogy ;), I want to share this:

I have found that my Zope would not start up when the servers mentioned
in a database connection object were unavailable (a ZMySQLDA in my
case). I "fixed" this by adding my db servers to the local /etc/hosts
file with an address of 127.0.0.0. Zope would start up fine then. The db
connections all appeared broken of course, but at least they were not
waiting "indefinitely" for a response from the servers.

This does of course not explain the quantum phenomena you saw ;)
