IBM, January 26

IBM's cloud credibility took a hit at the start of the year when a management portal used by customers to access its Bluemix cloud infrastructure (formerly branded SoftLayer) went down for several hours.

While no underlying infrastructure actually failed, users were frustrated in finding they couldn't manage their applications or add or remove cloud resources powering workloads.

IBM said the problem was intermittent and stemmed from a botched update to the interface.
