Port configuration is ambiguous..

We wouldn't have needed to do any of that - the reason for redundancy was not because we wanted it, but because our ISP insisted on it as part of the service (since the service came with a 6 hour SLA, after which they'd be paying out).

If the claims about diverse pathing turned out to be false, that would have been our ISP's problem - they'd have been paying out on a 6 hour SLA while chasing their suppliers to fix it ASAP.

And we'd agreed an SLA payout that was large enough that the business was better off with the Internet link down than with it up; we weren't foolish enough to believe that a "business" service meant it'd be prioritised for repair, but did believe that if we were getting more in SLA payouts than it was costing us to get alternatives (like LTE sticks for everyone), we'd be OK.
