(Reuters) – A global tech outage was disrupting operations across multiple industries on Friday, with airlines halting flights, some broadcasters off air and services from banking to healthcare hit by system problems.
Cybersecurity firm Crowdstrike said it was working with customers impacted by a defect found in a single content update for Microsoft Windows hosts.
Here are some of the biggest tech outages in recent years, in chronological order:
BRITISH AIRWAYS
IAG-owned British Airways was hit by a major computer system failure in May 2017 that stranded 75,000 passengers over a holiday weekend, sparking a public relations disaster and pledges from the carrier that it would do better in future. According to media reports, the blackout was caused by a maintenance contractor who accidentally switched off power.

Some of Google’s most popular services including YouTube, Gmail and Google Drive were down for an hour during an outage on Dec. 14, 2020.

In June 2021, thousands of government, news and social media websites across the globe were hit by a widespread hour-long outage linked to U.S.-based cloud company Fastly. The issue affected several high traffic sites including Reddit, Amazon, CNN, PayPal, Spotify, Al Jazeera Media Network and the New York Times with outages ranging from a few minutes to around an hour.
AKAMAI
Websites of dozens of financial institutions and airlines in Australia and the United States were briefly down on June 17, 2021, due to server-related glitches at content delivery network provider Akamai. According to the firm, the problem was caused by a bug in its software.
