On the other hand, it's not hard to maintain uptime when you have microsoft's resources to pour into failover and redundant systems.
Either way, the pingdom statistics are pretty meaningless. All it really tells us is that all of these sites (except Arch) are stable enough for visitors to not notice any downtime and that's what really matters. As for Arch, they could have switched providers or servers or whatever in this (too short) time frame and the result is probably not representative for the long-term availability.
If those linux distro sites encounter so much traffic as microsoft.com has every second, they will die in convultions. By the way, microsoft.com is a very large and sophisticated system, involving a lot of Windows and UNIX servers, with load balancing and caching from third party. Actually end user does not touch microsoft's hardware at all (:
What about RHN, it is under heavy use and traffic, I don't know where you get a few thousand people going to redhat.com they get a lot of traffic.
Plus, RHN is a entire model based off configuration, downloads, uploads, managing MS does not even come close to a scenario like that...
Most of the Windows servers we use in production (we use Windows and linux but we're slowly phasing out the former) do have poorer uptime than linux. That's nothing to do with traffic - they just need rebooting more often.
That's not an anti-Windows bias, just my experience. I imagine most folks working in a mixed environment would report something similar.
