Netcraft is a fascinating site all full of information about the Web. If you're not familiar with common Linux/UNIX networking tools, you might be a bit taken aback at how much you can learn about what other people are doing without ever leaving your comfortable computer chair.
One of Netcraft's most popular features is "What's that site running?" Look on the top left of Netcraft.com. Enter any URL, for example linuxtoday.com, and you learn all sorts of snoopy stuff in a nicely-organized Site Report. The Linux Today Site Report reveals that LT runs on Linux and Apache. The history only goes back to 2008, so let's see if snooping on LinuxPlanet turns up anything interesting. The linuxplanet.com report (not www.linuxplanet.com) shows that LinuxPlanet was running on Solaris/Apache until 2003, when it moved to Linux/Apache.
Linux Planet runs on Linux/Apache, but has an embarrassing uptime average- 19.29 days between reboots. Maybe the admins or devs have been doing a lot of work. Maybe someone clumsy trips over the power cord a lot.
We see that Linux Today has no uptime bragging rights either, with a current uptime of only 42 days. There is an uptime graph which shows a 90-day moving average of 57.55 days between reboots. However, that doesn't really tell you anything because LT resides on several load-balanced servers. So uptime has little relationship to availability. (Measuring uptimes is tricky anyway, due to peculiarities in the Linux kernel,as the uptime FAQ explains.)
