Google, AT&T, Amazon Web Services, Oracle Cloud Infrastructure and GoDaddy domain services were among the companies that started reporting outages on Thursday morning.

Gaming platforms Steam and PlayStation Network, travel services Expedia and Airbnb, shipping giants UPS and FedEx, and banking and financial institutions such as Chase, Discover, Capital One, Fidelity, and American Express were among others to report disruptions to their web services.
The problem appears to be due to an “emergency issue” with the Edge DNS service at the provider Akamai, which said it was “aware” of the problem and “actively investigating” it. The Domain Name System (DNS) acts as the internet directory, translating website names (URL) into IP addresses.
The Internet's Domain Name System (DNS) is supposed to be decentralized, but it's become concentrated among major providers.

Shortly before 1pm Eastern Time, Akamai issued an update saying it had “implemented a fix” that had resulted in the service ”resuming normal operations.” The company said the incident was “not a result of a cyberattack,” but occurred when “a software configuration update triggered a bug in the DNS system.”
