This.

They may not cooperate, in which case,  you have to force proof down their throats.

I would go with the Zenoss (or Zabbix, or...) option - a free to use, professionally supported, professional grade commonly used monitoring package that would meet anyone's basic "credible tool" definition plus neat GUI to send a snapshot of the results.

Use it to perform various tests of the net - pings, http gets of some small target, starting pings with the next hop outside your premise and working outwards to the outside world.  Don't overwhelm your net with tests, but test as often as needed to demonstrate an issue.
