Linux distros and Apple beat Microsoft's homepage uptime (Royal Pingdom)
The folks over at the Royal Pingdom blog have a comparison of uptimes and home page load times for the web sites of multiple Linux distributions along with Microsoft and Apple. Overall, the results of this month-long monitoring effort reflect quite well on Linux, but the authors are quick to caution that these numbers only reflect a particular point in time. Longer term monitoring is ongoing as well. "It is interesting to see that even with limited resources, many of the teams behind the various Linux distributions are managing a better homepage uptime and load time than Microsoft does, at least during this time period."

My home Exim4 mail server has better uptime than Gmail. But I imagine the loading is a bit lower on my machine, so it's not a fair comparison.

Gmail... which? Or do you assume gmail runs on a single server?

Pointless statistics, gathered over a stupidly short period of time using unscientific metrics, wildly skewed by known rare events, with little-to-no information about how they were gathered or what was actually measured, with no actual presentation of data, and no comparison of, say, how much traffic each site served in the measured time period.
This isn't even a primitive "rough" attempt at gathering statistics.
5m downtime - brilliant..., they even try to explain what it means at the bottom of the article - "not load within 30 seconds", were you measuring once per second, once per microsecond, once per minute, once per day and averaging out? The difference could be amazing. Were you adding to the load / contributing from the downtime by doing so? (e.g. you may well trigger anti-mirroring/QoS reactions on the servers). Were you measuring from one location or multiple locations across the entire world... they say that they check from "a second location", but no mention of how scientific that test is either (i.e. are you testing from both simultaneously from *different* carriers, different countries?). In the case of MS, which uses Akamai caching, surely downtime only means that a particular Akamai route has died?
Ask the people that you were *emailing* and publish their bandwidth statistics if nothing else... MS (actually, Akamai, which again skews the results) probably does 10-100 (if not 1000) times the traffic of even RedHat, even if you have complete ISO's for download on Red Hat (seen the size of the Windows XP SP's, not to mention things like MSDN). With mirroring, some of the smaller OS's may not even hit anywhere near the bandwidth limit of even the smallest, cheapest dedicated server.
I'm getting sick and tired of so-called "statistics", especially when the conclusions drawn ("OS-based companies keep their servers running better!!!") are so ridiculous, inflammatory and pointless. There is nothing in this article that could be used to draw even the stupidest of conclusions. I hope and pray that my children don't fall for this type of marketing rubbish (that really has no place on LWN.net) when they grow up.

Some meaningless numbers that were omitted from the article:
Average Linux distribution downtime: 2h 21m (compared to 2h 21m of Microsoft).
Average Linux distribution homepage load time: 932 ms (compared to 1173ms of Microsoft).

I think you will find that while the average microsoft downtime is 2 hours 21 minutes that average linux downtime is only 141 minutes

In addition to Microsoft using Akamai, so do Apple and RedHat. For that matter, I'm seeing images for Microsoft and Apple served by one of the same IP addresses. AFAICT, Microsoft and Apple (but not RedHat) actually run their own machines to serve their www hostnames, using Akamai to direct the traffic to an appropriate server.
