What do you do when there is a chance that you can cut off a million customers? This is the challenge that Yahoo faces as it upgrades its system to the more robust form of the internet - IPv6. The company estimates that at least a million users of its system will suddenly find themselves unable to access it because their home systems and networks are configured wrongly. The problem, of course, is that neither Yahoo nor the home user will know that a system is in jeopardy until the switch occurs. Yahoo is taking the right action technologically by making the switch. The world has about run out of addresses for the original protocol -- IPv4. It is just that no change as large as this can be clean. One hopes that Yahoo has a massive communications campaign in the works that starts months before the change and continues until months after. It will need all that and more.
