If you’re not a Blogrolling.com user this information is of no interest…
One of the benefits of the Blogrolling caching solution used at Wizbang (and available for your own use) is that I have a log of all of the times Blogrolling servers have been unreachable – for whatever reason. I was curious about the outages so I had a look at the logs. Here they are (edited for extraneous information) for the last month and a half:

That July 9th outage was a humdinger so I did calculations with and without that outage. All told it’s about 6 hours of downtime (or unreachability) out of 1080 hours (24 hours x 45 days), or an uptime of 99.3%. If you remove the July 9th outage the reliability increases to 99.9%.
Either way you owe it to yourself to be protected from slow loading pages by implementing the Blogrolling.com caching system.

That’s so cool that you did calculations. As a data analyst at heart, I think I love you. 🙂 Seriously though, that’s incredible reliability. It just doesn’t feel like that when it’s down. Thanks for the info on the caching system, again.
