Many major websites were briefly down in an outage sparked by a glitch in Akamai systems, the second major disruption linked to the cloud company in about a month.
"We have implemented a fix for this issue, and based on current observations, the service is resuming normal operations," Akamai said in a tweet.
The disruption lasted up to an hour and was caused by a bug in the domain name system (DNS) service, which allows web addresses to take users to their destinations, that was triggered during a software update, Akamai said.
Services resumed after rolling back the update, Akamai added, and confirmed the disruption was not due to a cyberattack.
"We are reviewing our software update process to prevent future disruptions."
Websites of Delta Air Lines, Costco, American Express and Aibnb were initially down, displaying DNS service errors.
Gamers were also impacted with the PlayStation Network being unavailable to some users despite the services operating.
“PlayStation Network services are up and running, but there are external, internet-wide issues that might affect your experience,” Sony said.
The Steam gaming service was also unavailable.
Oracle Corp and Amazon's AWS said the global issue related to Akamai's network impacted access to many internet resources, including their own cloud services.
Both Oracle and Amazon said their services were operating normally shortly after.
DNS is a service which lets users connect to websites on their phone or laptop, where a domain name is used to reach a cloud network to load content through an Internet Protocol (IP) address.
In June, multiple outages hit sites like Spotify, Reddit, The Guardian and the New York Times after a glitch with US-based cloud computing services provider Fastly.
It was later revealed the outage was caused by a single customer triggering an undiscovered bug in their system introduced a month before.
A similar thing happened in 2019 when Cloudflare deployed "bad software", forcing sites like Medium, Buzzfeed, Discord and Pinterest offline.
