Sainsburys have not been having much luck of late with regards to their online shopping service. The latest in an increasing line of outages is because thieves stole key equipment from the company's web hosting provider, Cable & Wireless (see here).
I've spent a lot of time over the past few years auditing and assessing the risk associated with online products. There's a consistent theme in many of my reports: lack of contingency and a lack of assessment of the company trusted to provide the hosting.
Nothing will stop the money flowing in faster than the product not actually being available for your customers to use. Common sense really. So, make no assumptions about your vendors and partners - check everything, and return to recheck on a regular basis too.
