Two years on, the 2013 National Security Agency (NSA) leaks are still causing companies worldwide to steer clear of storing their data in US clouds.
This is according to a new survey from Forrester Research, published on April 1st, in which almost 1,700 non-US firms were polled on whether or not they were still willing to partner with the country's cloud providers in light of events like Edward Snowden's disclosure of the PRISM online surveillance programme.
Asked if they had halted or reduced their spending with US-based suppliers in the past year over issues of security, more than a quarter (26 per cent) answered in the affirmative, the Register reports.
Of those respondents, 34 per cent said their actions had specifically been prompted by the Snowden leaks and "fear of intelligence community spying", meaning that almost one in ten (nine per cent) of all foreign firms had ditched US clouds following the disclosures.
Other reasons cited by the sample for repatriating their data included legal issues, as well as a preference for doing business with domestic cloud providers.
More generally, the survey showed that US-based suppliers are seen as less trustworthy than their counterparts elsewhere in the world, with a majority of the sample (53 per cent) saying they would prefer not to store any mission-critical data in the country.
Forrester concluded the report with the warning: "Your business partners are accountable to their governments and you can't expect them to put your interests above their own or those of their government."
Last year, a survey from the Cloud Industry Forum suggested that the Snowden leaks had done much to drive awareness of data residency among companies in the UK.
Almost a third (31 per cent) of the decision-makers polled told researchers they had moved their data "to where they know it will be safe" in light of the PRISM disclosures.
