FortiGuard Servers Down

Please try to change the fortiguard settings to these:

config system fortiguard

set fortiguard-anycast disable

set protocol udp

set port 53

set sdns-server-ip 208.91.112.220

set source-ip <WAN IP>

end

Other possible fix, at least it has worked in our company: Change System/Fortiguard/Fortiguard Updates/Update server location/ from "Lowest latency locations" to "restricted to" and choose "US only", then it works again with anycast still on.

Since Monday, same problem in France

The same problem occurred on firewalls in India last week, from February 23 to 28, 2025. We observed that it is intermittent. It is working fine in the US and UK regions.

Workaround:

config system fortiguard
set fortiguard-anycast disable
set protocol udp
set port 8888
end
