A global DNS outage related to the Akamai company made quite a stir on Thursday. The outage took down many websites and online services among which we can list Salesforce, Google, Amazon, AWS, Newegg, and PlayStation Network.
Who Is Akamai?
Akamai stands for an enterprise based on content delivery network (CDN), cloud services, and cybersecurity. Its services support the Internet and web security.
What Was the Cause of the DNS Global Outage?
As stated on Bleeping Computer, the issue seemed to be related to Akamai’s Edge DNS Service, which is an authoritative DNS solution hosted in the cloud whose role is to offer 24/7 DNS support and enhance the DNS receptivity, making websites, services and applications run properly and safely. Despite this discovery, Akamai extended its investigation.
The enterprise announced the server disruption immediately on Twitter and started working on it. However, it only lasted an hour, as per the representatives of the company’s declaration.
As per Akamai’s investigation, it resulted that the DNS system was affected by a bug related to a system configuration update that led to a system interruption for many client websites.

After further monitoring, the company came to the conclusion that this was not a cyberattack against the company and things should work fine from now on.
The disruption lasted up to an hour. Upon rolling back the software configuration update, the services resumed normal operations. Akamai can confirm this was not a cyberattack against Akamai’s platform.

What Is a DNS?
DNS or Domain Name System is basically the core Internet address book. Through domain names users access websites. For example, nytimes.com is a domain name. What DNS does it’s the fact that it translates the name of the domains into IP addresses.
