Several dozen sites of large groups were briefly affected Thursday by an outage encountered by the American technical supplier Akamai, which said it had restored its service.

At around 4.30 p.m. GMT, Akamai announced on Twitter that it had noticed a "disruption" in its customer service, without further clarification.

At the same time, several large companies, including American airlines Southwest and Delta Air Lines, were reporting difficulties connecting to their sites and applications.

Akamai provides various IT services, including cybersecurity and optimization services for websites, which, in theory, allow access to be maintained thanks, in part, to the cloud (remote computing).

Shortly before 5:00 p.m. GMT, Akamai announced that it had remedied the causes of this outage.

"We continue to monitor the situation and can confirm that this is not the result of a cyber attack on the Akamai platform," assured the group.

The title Akamai Technologies lost 0.50% to 117 dollars on the Nasdaq.

In mid-June, a worldwide blackout had already affected around 500 Akamai customers, who were deprived of internet connection due to a problem with one of the American company's security products.

The company, headquartered in Cambridge (Massachusetts, northeastern United States), then assured that the incident, which lasted four hours and affected several airlines and large banks, was not the made of a cyberattack.

In early June, Fastly, another provider whose name, like Akamai's, is almost unknown to the general public but which is essential in the accessibility and operation of many high-traffic sites, also experienced an outage.

The company, specialized in the "cloud", had explained that the incident, solved in less than an hour and which had notably affected the sites of Amazon or the New York Times, was due to a fault of one of its software.

The defect in question had caused chain failures after a Fastly customer updated their preferences.
