Amazon Web Services' Router 53 domain name system (DNS) service was waylaid by a prolonged distributed denial of service attack earlier this week, affecting a number of online sites and services that rely on AWS.

According to multiple reports, a flood of fake traffic disrupted legitimate attempts to resolve DNS requests to connect to Amazon cloud-hosted storage buckets and systems. The incident took place on Oct. 22 and stretched from around 1:30 p.m. ET to 9:30 p.m. ET, Amazon disclosed in a service update, according to reports. And at 8:16 p.m. ET, Amazon observed a very small sampling of specific DNS names that experienced a higher error rate.

"We're investigating reports of intermittent DNS resolution errors with Route 53 & our external DNS providers," AWS Support tweeted on Oct. 22 at 1:06 p.m. ET. Later, at 9:30 p.m., AWS Support tweeted that "The AWS DNS issues that may have affected your experience with Route 53 or our external DNS providers has been resolved."
