The Royal Bank of Scotland group of banks suffered nearly a <a href="http://www.bbc.com/news/business-33734168">fifty minute outage</a> to their on-line banking systems today as a result of a Distributed Denial of Service Attack. The banks affected included, Royal Bank of Scotland (RBS), NatWest, and Ulster Bank. A spokesperson from NatWest said in a statement "The issues that some customers experienced accessing on-line banking this morning was due to a surge in internet traffic deliberately directed at the website. At no time was there any risk to customers. Customers experienced issues for around 50 minutes and this has now been resolved."
