Sounds like a symptom of bad IT.
No contradiction from me on that.
Whenever IT gets beyond engineers managing their own machines, it tends
towards bad. Thankless job, that is not trivial, but usually tries to
run on lists of inflexible policies and procedures.
Something else I long ago observed: Because ethernet degrades gracefully it
always operates degraded.
Ethernet does NOT degrade gracefully. A graceful degradation would be: You
have 11 machines on a network together. 1 is a server, and 10 are clients.
All 10 clients hammer the server, and all 10 of them each get 10% of the
bandwidth that the server can sustain.
That would be "resists ambush robustly". I mean screwed up
configurations with broadcast packets going where they shouldn't and
collisions happening when they shouldn't and no one notices unless it
gets significantly bad, so it is always a little bad.
