If you ever wondered what server operating system is the most stable, check out this link. Maybe the average time between reboots isn't a perfect indicator of availability and stability, but there's one OS/web server combination on this list that's pretty impressive.
None of those sites are known to be heavy traffic sites. An OS comparision of those sites is what I'd be interested in.
http://uptime.netcraft.com/up/today/requested.html shows alot of well known sites. Note that they are not sorted by uptime.
"I dont know exctly what uptime is meassured"
That is being the reason we using the apachi and BSD
That's a silly reason to use BSDi, as the link states:
I don't think uptime should be seperated from high volume sites.
Server Uptime is a good idicator, but for the most sophisticated sites you'll have to manage, the big round numbers means jack *bleep*. No down-time could possibly be tolerated. To the customers, they care about your service uptime--in terms of response time and availability. If you expect to make them happy, you'll have to properly handle say the the downtime of a FreeBSD box that's usually up for 2+ years at a time just as well as you can properly manage a cluster of specialized server that may reboot multiple times a day and have service and software updates any time of the day. The key thing to remember here is that some people need to reboot their machine or mutate their service offerings all the time not because their vendor is Microsoft but because that's part of the service expectation or design. If you dig deep into it, few Linux and Microsoft web-database stack will ever be asked to handle a genuine live upgrade the way a telecom's specialized billing system requires. The illusion of uptime is only made complete because 1) there's clusters of these PCs, and 2) because the illusion of a session and usage is never maintained in the inherently stateless web/application servers but in the backend databases. Blah blah blah blah blah blah blah.. I will go go get a life.
Well if anybody I know has a linux or nt box up for about 500 days, I know they have a serious security issue. Who cares about the uptime of one machine?
This uptime obsession is one thing I really fail to comprehend. I have known shifty academic admins that refused to install some security patches because it would ruin their "uptime" streak. Gawwwd!!!
Just me (Sir to you)
