We rent two servers at 1and1.com to host our clients' websites. One of them just passed a major milestone: being up without reboot for over one year. Just a few minutes ago, it's uptime statistics were: 372 days, 12 hours, 39 minutes, the other reports being up 214 days, 22 hours, 17 minutes. So why aren't all our websites up 100% of the time? Well, this leads to a discussion of what parts of the digital pipeline between you and your website are reliable what percent of the time. We employ a monitoring service that checks the availablity of several of our sites from different places around the world. One of the sites we host, for instance, has a reported downtime of 5 minutes in this past month. But the server's been running along just fine for the past nine months? What went down?
