MaximumASP‘s Stacy Griggs paints an interesting picture of how to guarantee your website never goes down in his WHIR post last week.

He describes the pros and cons of 4 and 5 nine guaranteed redundancy well. Personally I prefer to view it as guaranteed uptime, or fault tolerance, and respectfully bring to readers’ attention to the recent possibility of 6 nine (99.9999%) uptime made real by fifth generation ftServers.

One reader questions the reality of 100% uptime. I advise that it really is not too far away and commend Stacy on a good post which scores highly on my usefulness and accuracy scales, regardless of the oversight in mentioning fault tolerance and the new 6 nines level of availability.

I encourage you to learn more about what it takes to achieve REAL fault tolerance by clicking the image below:
