Update 18.9.2023: The Problem has been solved. The servers are up and running again.
As we noticed, the FortiGuard DNS servers are offline at the moment.
Affected IP addresses:
Not affected IP addresses:
You can check, if the servers are responding to your DNS requests with the following windows and linux CLI command:
nslookup boll.ch 184.108.40.206
To temporary solve the issues caused by the timed out DNS requests, you can use other DNS servers on your FortiGate:
config system dns set primary 220.127.116.11 set secondary 18.104.22.168 end
Please use your preferred DNS servers for DNS resolution and replace the IP addresses listed above with your favorite DNS provider.
