In the A-office I'm using child-proxy which redirects requests to the parent1, and I want to make failover in case when internet line for parent1 is down to redirect requests to parent2 in branch2.
If you use ICP then this should be automatic after some time, when the parent detects it's Internet is not working and enters so called "Hit only mode". But this takes a while before it kicks in (there must be a significant amount of failed requests on that Squid for "Hit only mode" to be activated).
If the parents have a reasonably short connect_timeout then the failover should also be automatic. But at the same time this increases the risk of false failures when the origin web server is just slow at accepting the connection so it is not an universal solution to the problem.
