Thanks all for your input.
Nothing was getting logged into our servers in case of timeouts and
eventually it did turn out to be an external problem. The issue here was
that our university's boundary intrusion detection system parses GET and
POST variables and anything akin to "system (" or "eval (" is taken as an
attempt to a function call and its not let through.Thanks all, Vineet On Sun, Aug 16, 2009 at 7:44 AM, lists-php wrote: > I realized that this wasn't specific to the 404, but looking at > what's happening there would get most other things out of the way. > > If this only happens for connections from outside the network, > what's between the external user and these machines?
