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.

<div>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.<br>
