A study by internet services company Netcraft shows that something around 609,000 active servers still run on Windows Server 2003.

We’ll do the math for you: that’s a 12 year old operating system still powering web hosts for banks and security vendors. An operating system that – as of last month – Microsoft will no longer support. That means no patches or security updates whatsoever:

Those servers help run an estimated 175 million websites; Netcraft says they accounted for over a fifth of all the pages they surveyed.

About 55% of the machines were located in China and the US. That includes around 24,000 computers hosted by Alibaba, as well as several banks, including Natwest and ING Direct. Heck, even some security agencies like Panda Security and eScan are still running on the legacy OS.
