The cause of the outage, the latest major Internet outage this summer, was linked to Akamai Technologies, the global content delivery network based in Cambridge, Mass. Oracle, a cloud service provider, said its outage was the direct result of the Akamai disruption.
Akamai spokesman Timothy Whitman told The Washington Post that the company was making sure the fix held up.
“We will continue to monitor to ensure that the impact has been fully mitigated and can confirm this was not a result of a cyberattack on the Akamai platform,” Whitman said.
Delta, whose customers said that they were having trouble checking in for their flights, noted on its website that the airline was experiencing “temporary technical issues.”
DraftKings acknowledged that its site was down. “We’re aware of sitewide DFS and SB issues resulting in the app and full site not loading,” the company’s customer service team tweeted. “We’re working to have everything resolved and back to normal ASAP.”
Southwest Airlines, whose site was among those that also reported problems during outages in June, said the company was working on fixing the issue. “Our Tech Team has been made aware of the issues our Customers are encountering on Southwest.com and we’ll get it back up and running ASAP,” the company tweeted. “We appreciate your patience and understanding in the meantime!”
PlayStation Network games such as “Fortnite” and “Call of Duty” also were temporarily down. And other companies also took to Twitter to assure customers that their services would be restored.
The disruption comes more than a month after two outages struck large swaths of the Internet.
A June 8 outage, which affected companies such as the New York Times, Amazon and Hulu, appeared related to the San Francisco cloud services provider Fastly, which many companies use to help their websites load faster.
Then, on June 17, the sites for multiple airlines, banking institutions and trading platforms went down. United Airlines and the Commonwealth Bank of Australia were among those reporting outages, and the Hong Kong Stock Exchange also faced technical issues. Much like Thursday’s outage, the service disruption last month stemmed from a failure at Akamai. The company previously said that outage was due to a bug in a service used to mitigate distributed denial-of-service attacks.
Though outages at content delivery networks and Internet service providers generally get resolved rapidly, these disruptions — which have come amid pandemic-era shifts in people’s online habits — continue to underscore how these incidents can bring huge parts of Internet life to a halt.
