Pingdom AB, a Swedish-based website monitoring firm, recently studied the uptime of the update sites for the three most popular desktop operating systems, Microsoft, Apple, and Ubuntu. During the second quarter of 2008 (April-June), Pingdom reports (2) that Windows Update was up 100% of the time, compared to Apple Software Update's 99.9% uptime, and Ubuntu Archive's 98.64% availability. During the period, Apple's update service could not be contacted for a total of 2 hours, 34 minutes, while Ubuntu's update service could not be contacted for a total of 1 day, 5 hours, and 45 minutes.
It sounds like a clear win for Redmond, but a closer look at how update sites work suggest the story isn't so simple. For more, join us after the jump.
