Information Week reports on an analysis by the web monitoring firm Pingdom, which revealed that Microsoft has the most “reliable” update service, better than Mac, and much better than Ubuntu. Microsoft’s update service had an uptime of 100% in the second quarter of 2008, while Mac’s was 99.9%, and Ubuntu’s was 98.6%.
Of course, this single metric doesn’t tell you much about the overall quality of the update service. How about the quality of the updates themselves? How many vulnerabilities were fixed, and how many vulnerabilities were introduced that need further patching? How about the length of time that it takes to get updates, especially those that address critical security vulnerabilities, out to the public? I’d rather have to wait a couple of hours to get an update because the server is down than to wait weeks or months because the software developers haven’t completed the patches. The fact still remains that updates take significantly longer to get to Windows users than to Ubuntu users, and GNU/Linux is still a more secure operating system. Pingdom’s analysis is worthless.
