Depends on what you do. The company I work for does outsourced datacenter operations and application monitoring. Our site and our blog absolutely must be up at all times, period. If one of our blog posts made it to the front page of HN or reddit and we weren't able to handle the load, or God forbid we went entirely offline, there would be some serious egg on our faces. Why should potential or current clients trust our advice about how they can stay online if we can't do it for ourselves?
