High availability is a network design issue not an OS issue. All OSes
can be and are high availability. It does not matter how reliable are
these servers [Windows, Linux, FreeBSD, Solaris... are all reliable
today], if the network is down!

Having a couple of servers on the west coast and another couple on
the East coast on different carriers [if in North America], with
proper DNS configuration will make this a very high availability. 

Then comes: how are these servers protected? With a proper firewall,
or a they naked on the Internet [naked is my preference, because they
will be configured with the minimum of services.]

Using squid are a reverse proxy will enhance their security and
therefore availability. 

What will you be running on these boxes? Apache, IIS, PHP, Perl,
Java, .Net. Any dayabase? ... This is far more important in
availability that which OS.

There are many more things to look at. That why you need a good
consultant ie: $$$...
