XG 330 REV.2 WAN Gateway Reports, Down & Up

Question

Hi Everyone, 
 Are any of you guys/gals having your XG report your external WAN as down or up over and over again ? I have called my ISP to verify everything on their end during the times I got the notifications. They said everything is good and I even had a tech come out and physically check the connection coming in and he said everything was fine as well. (no packets lost either) I'm sure this is some kind of system glitch because when it says its down, I immediately check for internet access and everything is fine. Just this morning I woke up to a slew of emails stating the status was up and down. It happens almost everyday at random times of the day and more when I am not on site of course. 
 
 Any suggestions ? Specs/Info below: 
 XG 330 Rev 2 
 Firmware: SFOS 17.1.3 MR-3 
 Max CPU Load: 6% 
 Max MEM Load: 22%-29% 
 HA Mode = False 
 Load Balancing = False 
 
 A screenshot of the emails I received recently.

Thanks for reading.

Hi, 
 you need to check what you are using in the WAN link manager as your test site and change it to something more reliable.

In WAN Link Manager, you can edit the gateway and there you will find something called "Failover rules". 
 https://community.sophos.com/kb/en-us/123530 
 Configuring failover condition 
 Upon adding a gateway, Sophos Firewall adds a default failover rule indicating that if it is not able to ping the recently added gateway IP address, then this gateway is considered down.
