Dozens of consumer websites were reported to be offline or slow to load on Thursday afternoon, creating headaches for people trying to gain access to their accounts, but the issues were resolved shortly after.
A range of companies had outages, including financial firms like American Express and Chase, retailers like Amazon and Home Depot and travel companies like Delta Air Lines and Expedia, according to the online platform Downdetector.
On its website, Delta said that it was working to resolve “a technology issue” that was affecting “many global websites.”
“You can continue to check in for flights at this time at the airport,” Delta’s statement said.
The outages were reported as Akamai, one of the largest cloud-computing providers, said it had experienced problems with its DNS service, though it wasn’t immediately clear whether the Akamai outage was the source of all of the issues elsewhere. DNS, one of the most fundamental technologies of the web, helps route requests for a specific URL to the server where that website actually lives.
Akamai also helps many companies make their sites faster and more reliable by serving cached versions of pages from around the globe, but an outage in its network could render those sites unusable.
Akamai confirmed the connectivity issues were not the result of a cyberattack.
“There are reports of issues related to a Content Delivery Network (Akamai) outside of Amazon’s Network,” Amazon Web Services said in a statement posted on its website. “We have investigated AWS services such as Amazon Route 53 and Amazon CloudFront and these services are all operating normally at this time.”
Zomato, an Indian food delivery company, also blamed Akamai for its outage. “Our app is down, owing to a widespread internet outage (Akamai),” the company posted on Twitter.
Just before 1 p.m. Eastern time, Akamai said it had resolved its issue.
“We have implemented a fix for this issue, and based on current observations, the service is resuming normal operations,” Akamai said on Twitter.
In an apparently unrelated incident, several counties in Virginia, including Campbell and Grayson, reported that their 911 systems were down. On its Facebook page, the Grayson County Sheriff’s Office said the outage was because of a cut to fiber internet lines and that 911 could still be reached from landline telephones.
