Visa admits 5m payments failed over a broken switch
“We operate two redundant data centres in the UK, meaning that either one can independently handle 100% of the transactions for Visa in Europe. In normal circumstances, the systems are synchronised and either centre can take over from the other immediately … in this instance, a component with a switch in our primary data centre suffered a very rare partial failure which prevented the backup switch from activating.”
