BA's 'global IT system failure' was due to 'power surge'
Found on The Register on Monday, 29 May 2017
The "power supply" issue was a power surge that occurred at a BA data centre on Saturday at 9.30am, Cruz has said. "We will make an in-depth investigation to make sure we get to the bottom of exactly why this happened and we will react absolutely, this will not happen again at British Airways."
If a company as big as British Airways relies on a single datacenter for their global operations, they are doing something wrong. This works for smaller sites, but if you completely depend on the systems, you want to avoid the DC as a single point of failure.
