45% of UK companies have experienced down time due to natural causes.
Half of organisations are not prepared to keep their data centre up and running in case of a natural disaster, according to Zenium Technology.
The "Managing Growth, Risk and the Cloud" report unveiled that on average disruption occurs every two years, with 45% of UK companies experiencing problems with their data centre.
91% of the enterprises surveyed experience incurred expense every time services go down, with the maximum cited as £500,000.
The survey also found that 34% of CIOs, VPs and directors do not know what the "exact" cost was, and said that ‘some’ loss was incurred.
Organisations that outsource were found to be less likely to face disruption than the ones that do not outsource, with 25% and 58% of organisations affected respectively.
86% of IT professionals in the UK considering outsourcing said they would prefer to host data in the country.
The report shows that 45% of respondents said their data centre is flood resistant, 43% confirmed facilities are earthquake resistant and 60% declared their data centre is located in an area away from physical or environmental hazards.
Franek Sodzawiczny, CEO at Zenium Technology, said: "Natural disasters are rightly top of the data centre business agenda and I believe that outsourcing continues to offer a viable risk-reduction strategy.
"The report found that 83% of respondents believe they will have to lease more data centre space from domestic providers as a result of the EU Data Protection Directive so making the right decisions about the data centre will continue to be about ‘location, location, location’ in the long term."
