A wave of brief internet blackouts hit the websites and apps of dozens of financial institutions, airlines and other companies around the world on Thursday.
The Hong Kong Stock Exchange said in a tweet Thursday afternoon Hong Kong time that its site was experiencing technical issues and was investigating. He said in another article 17 minutes later that his websites were back to normal.
Internet monitoring websites including ThousandEyes, Downdetector.com and fing.com have shown dozens of disruptions, including for US-based airlines.
Numerous blackouts have been reported by Australians trying to bank, book flights and access postal services.
Australia Post, the country’s postal service, said on Twitter that an “external outage” had impacted a number of its services and that although most services have returned online, they continue to monitor and to investigate.
Many services were up and running after about an hour, but the companies affected said they were working overtime to avoid further problems.
Banking services have been severely disrupted, with Westpac, the Commonwealth, ANZ and St George, as well as the Reserve Bank of Australia website.
Most of the services have been restored.
Virgin Australia said flights were largely functioning as intended after it restored access to its website and contact center for guests.
“Virgin Australia was one of many organizations to experience an outage in Akamai’s content delivery system today,” he said. “We are working with them to ensure that the necessary steps are taken to prevent these outages from happening again. “
Akamai counts some of the world’s largest corporations and banks among its customers.
Appeals to Akamai, which is headquartered in Cambridge, Massachusetts, but offers global services, went unanswered.
The disruption came just days after many of the world’s largest websites were briefly offline due to an issue with software from Fastly, another large web services company. The company blamed the problem on a software bug that triggered when a customer changed a setting.
Brief Internet service outages are not uncommon and are rarely the result of hacking or other mischief. But the blackouts have underscored just how vital a small number of companies behind the scenes have become to harnessing the internet.
