Another significant Internet outage hit major online platforms along the East Coast of the United States on Thursday, July 22, knocking off high-traffic websites like Amazon, Airbnb, FedEx, and Delta Air Lines.

Shortly before noon EST on Thursday, Down Detector, a tool that monitors whether websites are working properly or not, began reporting a sequence of at least 50 large website outages, Daily Mail reported.

Among the other potentially affected websites on Thursday were Home Depot, Airbnb, US Bank, FedEx, UPS, Fox News, American Airlines, Delta Air Lines, AT&T, Groupon, Expedia, HBO Max, and TikTok, according to Down Detector.

Interactive Brokers, Santander Bank, BBVA, and BB&T, were among the worldwide financial organizations that looked to be damaged.

Amazon Web Services and Oracle Cloud are both down, according to Down Detector, but the Amazon Web Services website looked to be up and running.

Over 3,500 people reported troubles with Airbnb’s website, while roughly 1,500 users reported issues with Home Depot.

The source of the outage, which was the most recent big Internet outage of the summer, was traced back to Akamai Technologies, a global content delivery network situated in Cambridge, Massachusetts. Oracle, a cloud service provider, stated that its downtime was directly caused by the Akamai outage.

In a statement, Akamai Technologies indicated that a software update caused a flaw in its DNS service, which caused the outages, and that the problem was not caused by a hack.

“The disruption lasted up to an hour. Upon rolling back the software configuration update, the services resumed normal operations,” Akamai said.

“Akamai can confirm this was not a cyberattack against Akamai’s platform,” the company added.

Last month, a separate significant internet outage was blamed on a similar issue with one of Akamai’s competitors, Fastly.

Fastly said at the time that the problems on June 8 were caused by a “undiscovered software bug” in its system, which was caused by a single anonymous client updating their settings.

Meanwhile, at least nine counties and three cities in Virginia reported 911 outages or call difficulties on Thursday in what appears to be a separate issue.

“There appears to be a multi-state 911 outage. The issue is being addressed,” the Rockbridge County Fire-Rescue & Emergency Management said in a statement. 

According to the Department of Public Safety in Campbell County, Virginia, all service to the county’s 911 and non-emergency phone lines has been disconnected.

WSET-TV reported that a cut fiber optic cable in Greyson County was possibly to blame for the emergency services outage, which looked unrelated to the internet problems.

According to the Greyson County Sheriff’s Office, CenturyLink was attempting to repair the cut fiber in the Marion area.

However, conflicting reports suggested that the Akamai event was responsible for at least some of the 911 disruptions in Virginia.
