AMSTERDAM, March 25, 2010 /PRNewswire/ -- WatchMouse (http://www.watchmouse.com/en/), a global industry leader in self-service website and application performance monitoring, tested the 50 websites belonging to the companies listed on the ASX 50, the benchmark stock market index of Australia's stocks listed on the Australian Stock Exchange, for availability and performance. Only two of the ASX 50 company websites registered 100% uptime. The websites with the lowest uptimes included Wesfarmers Limited (36.2%), Crown Limited (61.5%) and Tabcorp Holdings Limited (90.6%). The websites with the best uptimes included Macquarie Group Limited (100%), News Corporation (100%), CFS Retail Property Trust (99.9%) and Rio Tinto Limited (99.9%).

These are the largest public companies in Australia and only four of their websites met the industry standard of 99.9% uptime or greater, and Wesfarmers with only 36% uptime is abysmal, states Mark Pors, CTO and co-founder of WatchMouse. We also noted in our research of 10 other global market indexes that Australia ranked at the bottom of the list when it came to website uptimes.

WatchMouse monitored the websites during the period of February 22 to March 23, 2010. According to industry standards, availability of greater than or equal to 99.9% is regarded as good while anything below 99% is regarded as poor site uptime.

The sites were checked every five minutes during the test period from one of the 42 WatchMouse global monitoring stations, and included a retrieval of the website home page, without graphics or frames. The home page was expected to load within eight seconds without any errors. If that time was exceeded or a server error occurred, WatchMouse verified the results using another of its monitoring stations. The result was counted as either poor availability or unavailable if a second error was established.
