The device that caused this whole conversation has failover
functionality. Both interfaces ping an FQDN (that resolves to 8.8.8.8
and 1.1.1.1, with the device only latching on to one of those). If any
of those meet the failure threshold, that interface is taken out of
the traffic flow.
So because someone else built a device (without a meaningful
configuration to set otherwise), 8.8.8.8 went down for ICMP, and thus
Internet ports began flapping, despite the Internet as a whole working
just fine.
Pretty amazing, isn't it?
