Many of the companies that provide electricity to the grid are not running windows to power their systems, they are still running everything on UNIX. They simply cannot upgrade because they have a 100% up-time requirement.

We have fully redundant instant-failover servers. We can upgrade anytime we feel like it, with NO downtime.
