WAN Down but logs show DDNS updated and DNS lookups successful

Question

My WAN has been down for hours but the DDNS logs show the updates are successful. And the firewall logs show success for DNS lookups. How can that be?

Hey Brian1941 It might have been a DNS cache resolver that made it work, thus concluding this thread

Hello Brian1941 , Thank you for reaching out to the community, have you created an static DNS host entry ?

Hey Brian1941 ,

Can you share the screenshot of the DDNS configured ?
Can you also share the ddc.log and dgd.log during the same time when WAN was down but DDNS got updated.
To check the log file use the doc for the reference.
