Update: Akamai has resolved its service disruption which it explained was the result of a software configuration update that triggered a bug in its DNS system.

Major websites and online services including AWS, Google, Salesforce, Cloudflare and others were taken offline as a result of a DNS (opens in new tab) outage at the global CDN (opens in new tab) provider Akamai (opens in new tab).

According to a notice (opens in new tab) posted on the company's site, an Edge DNS service problem was to blame and the incident has now been mitigated.

In addition to its Edge DNS Service Incident notice, Akamai has been updating its customers regarding the situation on Twitter. In a recent tweet (opens in new tab), the company explained that while the service has been restored, it's still keeping a close eye on things, saying:

“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.”

Edge DNS outage

Akamai's Edge DNS service is a cloud-based DNS solution built on a globally distributed Anycast network that is designed to provide 24/7 DNS availability while also improving DNS responsiveness. The service also offers businesses and site owners with the resilience to defend against large-scale DDoS attacks (opens in new tab).

While the outage at the company now appears to be resolved, the incident affected almost 50 popular websites and online services according to Downdetector (opens in new tab).

Among the sites that saw issues or outages were:

  • AWS
  • Amazon
  • Cloudflare
  • Google
  • Salesforce
  • Oracle
  • Verizon
  • AT&T
  • Xfinity
  • T-Mobile
  • FedEx
  • UPS

Popular gaming services including the PlayStation Network, Xbox Live, EA, Origin and others along with games like Fortnite and Apex Legends were also affected (opens in new tab).

If today's incident seems at all familiar, that's likely because competing CDN provider Fastly (opens in new tab) also experienced a similar worldwide outage (opens in new tab) just last month.
