Right now I'm dealing with a situation in which my company has two redundant
frame relay links to Botany Australia. One through Sprint, and the other
through AT&T. We were experiencing really bad latency on the AT&T link (up
to 1.2 seconds), so I moved all the traffic over to the Sprint link once it
was installed. No change, though, in the latency. I used Concord Net
Health to measure the latency, and it was *exactly* the same over both the
AT&T link and the Sprint link - they spiked at the exact same times, and to
the same degree. They must be going over the same satellite link or
whatever, but *something* is amiss here....

The world is a single point of failure. :->
Seriously, something often overlooked - the ISP's themselves, their
backbones, their peering.
Not too long ago, up in the Sacramento area, some folks found out the hard
way that even though they were dual homed, both ISP's used the same backbone
provider. When that provider had a failure, both ISP's were down ( along
with several others in the area, all of whom used this same Tier 1 as their
backbone )
If the customer really does require "absolute complete redundancy" then you
and they should be doing a lot of research.

I have a client who needs "absolute" complete redundancy for their Internet
service.
I assume they should be using 2 separate links with different ISPs. What I
don't have hands-on experience with is the physical connections and HSRP.
Will I connect both routers to the local switch and then configure HSRP
between them?
Any help would be greatly appreciated.
