Major banks and airlines were among the businesses hit by a fresh global online outage on Thursday, with the problem traced to US tech provider Akamai.
An hour-long blackout hit several US airlines and Australian financial firms as well as other companies dotted across the world, with angry customers unable to access websites and cellphone apps.
"We are aware of the issue and actively working to restore services as soon as possible," an Akamai spokesperson said.
American, Delta, United and Southwest airlines were among those affected, while the issue appeared to be more prolonged in Australia -- where problems struck mid-afternoon as much of the world slept.
Australia's largest financial firm Commonwealth Bank said it and many of the country's major lenders had been hit.
The outages, which began around 2.10pm Sydney time (5.10am GMT), also hit Australia's postal service and Virgin Australia.
The airline said it "was one of many organisations to experience an outage with the Akamai content delivery system".
An ANZ bank spokesperson said the incident was "related to an external provider" but that "connectivity was restored quickly and the most impacted services are back online".
Banks in New Zealand and the Hong Kong Stock Exchange also reported problems with their web platforms.
It is the latest incident to draw attention to the stability of economically vital online platforms and the key role that a handful of mostly unknown companies play in keeping the web running.
Last week US media and government websites, including the White House, New York Times, Reddit and Amazon, were temporarily hit after a glitch with cloud computing services provider Fastly.
Fastly offers a service to websites across the world to speed up loading times for websites.
Akamai offers a range of similar IT products designed to boost online performance and security.
The Cambridge, Massachusetts, company refused to comment on what product the problem came from, but one of the affected firms reported it used Akamai for "IT network authentication".
Among the services Akamai provides are platforms that prevent DDoS attacks -- an often crude cyberattack that knocks websites out by peppering them with requests for data.
"Our priority is restoring service as quickly as possible. We will share additional information as it becomes available," an Akamai spokesperson said.
A series of high-profile hack-for-ransom attacks have also left corporations across the world jittery over cybersecurity risks, although there was no indication the latest problems were caused by malicious actors.
Colonial Pipeline was briefly shuttered after an attack last month, and JBS, the world's largest meat producer, was forced to stop operations in the US and Australia.
Both firms reportedly paid ransoms to get operations back up and running.
The issue of cybersecurity was at the top of the agenda when US President Joe Biden and his Russian counterpart, Vladimir Putin, met in Geneva on Wednesday.
Washington believes hackers who have extorted hundreds of millions of dollars from Western governments, companies and organisations operate from Russian soil.
