In the February 2003 survey we received responses from 35,863,952 sites.

One of the goals of Apache/2.0 was to better support operating systems other than Unix. While the Windows version of Apache/1.3 was advertised as experimental, it was hoped that in Apache/2.0 it would become much more widely established. However, since the first general release of Apache/2.0 there have been a string of security problems in the Windows (and other non-Unix) versions that may undermine confidence in the suitability of Apache for these platforms.

Windows Apache entries listed at mitre.org's common vulnerabilities database include directory traversal using dot-dot paths, revealing script source by appending invalid characters, and DOS device names causing a denial-of-service. The striking thing is that these are sterotypical vulnerabilities that over the years many other products have suffered from, and fixed. Apache developers will be disappointed that they were not able to learn from other people's mistakes sufficiently well to pre-empt the same vulnerabilities appearing in their own server.

In the current month's survey we find over 16,000 Apache Win32 sites on the 'Web which may be vulnerable to one of these problems.

Notwithstanding the security problems, the support for threading in Apache/2.0 is a major performance breakthrough for the Windows version and consquently sites using Apache on Windows have a bigger incentive to upgrade to version 2 than sites on Unix. This is reflected in the relative uptake of Apache/2.0: a little over 1% of all Apache sites are running version 2, but amongst Windows servers the proportion is over 7%.

Last month we pointed out a Windows 2000 site that had gone over two years without a reboot.

Unfortunately, www.byteandswitch.com's proud run came to an end coinciding with the SQL-Slammer worm at the end of January.

• When we say "Upgrade!" you must do what we say, not do what we do
• We're still waiting for our order to be delivered
• It's not broke, and we dont need to fix it.
• We're less of a target for attackers. There's no kudos in hacking anything more than 5 years old.
• We've been evaluating Linux, and have not yet reached a decision.
• It's just the front end machines. Everything else has been running Windows 2003 for months. Honest!
• The cobblers children didnt have shoes, either.
• That site doesnt see a lot of traffic. It just redirects to www.euro.dell.com
• If you think that running NT4 doesnt do a lot for our product advocacy, then you haven't seen what our evil competitor runs
