One in six IT leads estimated their company would lose $1,000,000 (just under £600,000) for every hour of downtime, a study shows.
Further, 60 percent of all respondents said that downtime cost up to $500,000 (£300,000) due to lost sales, data and productivity.
The GlobalSCAPE survey of 283 IT professionals and business end users found that nearly 90 percent of organisations unexpectedly lose access to critical systems, including mail servers, back-end processors, and file servers.
Almost a third encounter downtime once a month or more.
James Bindseil, president and CEO of Globalscape said: "Downtime, while understood to be tremendously costly and frustrating, has become commonplace and even expected in the enterprise. Oftentimes, downtime can be avoided, and companies should expect more from their vendors."
The findings revealed that active-passive clustering didn’t guarantee high availability. All respondents with active-passive clustering environments lost 34 percent more data and critical emails than IT professionals with active-active.
"Companies need an 'always on' solution that can protect their businesses and customers," said Bindseil.
