alert "interface wan1 dead, related policy route rules will be disabled

Hi community
today we noticed that our internet connection was down for some time. In the USG60 (firmware 4.7) log we got the alert:

>Interface wan1 dead, related policy route rules will be disabled<

>Trunk SYSTEM_DEFAULT_WAN_TRUNK dead, related policy route rules will be disabled<

does anybody know this issue or by what it is caused?

 I'll keep up monitoring and will check if this issue occur again
 many thanks in advance for your support

This is normal behaviour when e.g. your Internet Connection fails due to different reasons.

For example, we experienced problems when USG tried to renew its DHCP lease with ISP's DHCP server. Since the lease has not been renewed, the USG lost its IP and the interface WAN1 went dead. And in case you do not have a second internet connection (e.g. for load ballancing or failover) the entire WAN trunk is dead.

With us, since we got a second ISP, the internet failover switches over to WAN2 and the WAN trunk didn't go dead.
