User Question: We have 2 Internet connections and when the Internet went down it didn’t failover to the backup line. Our IT guy said even when setup right it wont switch over 100%. Is this accurate or was it setup wrong?
Answered BY A CTO: Excellent question that we run into quite often. First of all, it of course depends on the firewall you have, the license on it, and the configuration that is setup on the firewall. However, even if everything is good, and the Internet failover is setup right and working, I do agree, it won’t work 100%. If the primary ISP is down, but the issue is in their datacenter (also called a CO / Central Office) the firewall might still see the primary connection as UP and RUNNING, so it won’t failover. Because it is receiving power and is actually connected, it just can’t follow the whole path needed for Internet access. So in short, it is definitely possible.
