The web pages of several major companies including Amazon, AT&T, UPS and US Bank were briefly impacted by an apparent outage Thursday.
According to Downdetector.com, a website that tracks internet outages, the problems began for several websites late Thursday morning.
The cause of the outages is not known at this time. Internet company Akamai acknowledged the outage on its website saying they "are aware of an emerging issue with the Edge DNS service and that they are "actively investigating the issue."
As services began to get back online, Akamai tweeted, "We have implemented a fix for this issue, and based on current observations, the service is resuming normal operations. We will continue to monitor to ensure that the impact has been fully mitigated."
The Cambridge, Massachusetts-based company told WCVB that the outage was not the result of any cyberattack.
This is the third major internet outage in two months, and the second involving Akamai. In early June, dozens of websites including Target, the New York Times and a UK government website went down for around 50 minutes because of a widespread failure at content delivery network Fastly. Ten days later, airlines, banks, stock exchanges and trading platforms suffered brief outages, which Akamai said was the result of a bug in a service that helps mitigate distributed denial-of-service attacks.
Major website and app outages happen from time to time and typically don't last long. Internet service providers, content delivery networks and other hosting services are built with multiple redundancies and a global network of backup servers designed to reduce disruptions when things go haywire. However, the recent outages have caused some experts to warn of the risks of the internet's reliance on a relatively small number of core infrastructure providers.
