Huh. My Ubiquiti was reporting WAN link down during this outage. I'm using ATT fiber. I'm wondering if "link down" doesn't mean what I think it means. Now that I check, it says "WAN iface [eth2] transition to state [inactive]". I'm wondering if that means link down or if it's doing service checking. I actually have a WAN2 configured but not plugged in and it was set to "Load Balancing: Failover Only" ... I wonder if all of my 'connection issues' were software assuming my network link is down and switching interfaces to an unavailable one.

to reply to myself, if you have a second interface configured for failover, it actually tests against ping.ubnt.com. I bet every single time my ATT fiber has "gone out" for a minute or two at a time, it's been bogus. root@USG-PRO-4:~# show load-balance watchdog Group wan_failover eth2 status: Running pings: 2 fails: 0 run fails: 0/3 route drops: 0 ping gateway: ping.ubnt.com - REACHABLE eth3 status: Waiting on recovery (0/3) failover-only mode pings: 1 fails: 1 run fails: 3/3 route drops: 1 ping gateway: ping.ubnt.com - DOWN last route drop : Fri Jul 17 17:32:58 2020
