The computing cloud we have created supports much of our day-to-day office and leisure activity, from office email to online shopping and sharing holiday photos. Even health, social care and government functions are moving towards digital delivery over the internet.
However, we should be wary that as we become more dependent on it, the cracks will show. The systems are often a patchwork of interconnected services provided by various companies and industry partnerships. A failure of one can lead to a failure in others.
For example, Skype recently went down for almost an entire day, while Facebook was down for more than an hour – the second time in a week – meaning that many sites that depend on Facebook accounts as authentication were locked out too.
