!!!

My intended point was that Akamaized sites are less likely to be
overloaded than non-Akamaized sites.  Traffic spikes from
incidents such as the release of the Starr report and the
bombings last month have demonstrated this.

Given enough hosting points, overloading becomes rare; I used
Akamai as a real-life example.  Given that overloading is rare,
we can focus on failover, and worry less about load-balancing.
Given that we need only to focus on failover, the problem (and
hopefully the solution) becomes much simpler.

I'd hope that the average NANOG reader knows better than to try
any "let's see how much traffic before this breaks" stupidity...
