How I would do it:
* Single server connected to all three
* Policy routing configured such that packets with the source IP
corresponding to each ISP is routed to their gateway.
* Some scripts to monitor each link, and add/remove them as default
gateways depending on their status..
* Multi-path routing enabled in the kernel, allowing for multiple
default routes and load sharing among them.
See http://lartc.org/howto/lartc.rpdb.multiple-links.html for details.
With this in place Squid will run happily, completely ignorant to how
many links you have and instead letting the OS sort it out.
