This latest outage comes just four months after Microsoft suffered an outage described as the “worst IT outage the world has ever seen.”
The outage affected supermarkets, banks, telecoms companies, streaming services and PCs, with airports, railways and GP practices also reporting problems.
It later emerged that the problems were caused by a glitch in the Crowdstrike cybersecurity service used by Microsoft.
The Microsoft outage was caused by a bug in the Crowdstrike software update, which was implemented in the ‘Falcon Sensor’, which searches for viruses and malicious attacks.
The resulting disruption left millions of passengers stranded at airports, while major airlines grounded their planes.
