Has hell frozen over? Or is Windows Server more reliable than Linux?

For the last week, according to Netcraft, Windows is #2 behind FreeBSD for web servers and it outnumbers all other OS’s in the top 50. Linux isn’t even on the list?

See the list for yourself. The list is limited for the most requested sites due to notability and performance reasons.

Either MS has done a bangup job convincing sys-admins to keep their servers up to date and secure, or Linux is starting to slip a little. This is the first time I’ve seen BSD being threatened in the weekly averages and Linux completely falling of the list.

FreeBSD in particular is one of the most stable (arguably the most stable) platform for servers so no surprise there. But Windows Server?!

  1. I don’t agree that you can treat uptime is the only one factor of reliable or stable. Uptime is only showing how long has this system been running after last boot, but not why did this system had to reboot.

    There are many reasons that a system needs to reboot. For Linux, kernel update is one of those, but it’s up to the admin. And you can’t count kernel update as unreliability but you may count it as unavailability. Because kernel update is part of maintenance.

    I guess Windows’ updates mostly don’t need to reboot or Windows doesn’t report correct uptime or netcraft can’t detect Windows’ reboots and only happen on Windows system.

    Anyway, Uptime != Reliable, but a factor of that at most.

    • I agree that uptime is only a factor of reliability and reboots may or may not happen due to updates.

      But I don’t agree with this :

      I guess Windows’ updates mostly don’t need to reboot or Windows doesn’t report correct uptime or netcraft can’t detect Windows’ reboots and only happen on Windows system.

      …That is pure conjecture.

      Netcraft has been a very reliable source of server information for a very long time. If it wasn’t, the Apache foundation wouldn’t quote its stats for the HTTPD project. Nor would certain Linux distributions tout it as a source of data for market penetration.

      From the “BSD/OS” signatures, it is clear that certain admins take steps to obscure their particular server version. On certain other stats I’ve seen, the HTTP server is also masked. But uptime is not something that is fiddled with.

      • Yes, it’s pure conjecture. That’s why I used “I guess”.

        If you read the faq http://uptime.netcraft.com/up/accuracy.html

        Each site that is in the set of sites to be monitored is queried only once a day. We only do this once, and if the site is unavailable at the time we do it then it will not have a sample recorded that day.

        you may want to calculate the probability if the site only on 1 hour each day, the monitor contacts once a day in given time as uniform distribution over 24 hours, and get 30 consecutive times of success.

        Yes, many people and organizations quote their analysis, but did anyone ever mention the accurate or the probability of error? You know, when a market survey result is released, they also mention the sampling error.

        But back to the results you mentioned in post above, there must be some reasons that no Linux servers can make themselves on the list. “The reasons” should be what we concern not the %, though % is important too. I believe it’s not about reliable. Again, it’s conjecture.

      • I called it conjecture, not because I missed the “I guess” part… It’s because you only mentioned scenarios for why Windows was on the list. Not why Linux wasn’t.

        Now, your next comment does contain useful information on why Linux may not be present. So thanks for that…

  2. I like the “Protected Mode: Off” on the bottom panel of your IE window. It makes me think of a screen door on a submarine’s outer hull, except that the door is also wide open. :P

    • HAHA! Don’t worry, I was planning to scuttle the u-boat to keep it off enemy hands. ;)

      This was actually on a laptop that I have a habit of wiping every week or so. It’s a paranoia thing…

      I don’t browse the Internet on my “work” machine. :P
