So I can't list them all here. Over time your techs should collect them all but your techs should get some top 10 to work with. It's not a mystery at all but given the rather long list of causes I won't type them all here.
Here's a thing though. I'm finding folk are growing impatient with how things work. If the machine boots up and takes a minute to get a good IP then some will call that a failure. You may have to develop a good script to talk about how things are sometimes not instant.
