In the early hours of Thursday, April 21 various websites including HootSuite, Reddit and Foursquare were offline due to Amazon AWS server issues.
The issue involved Amazon’s cloud computing platform which was experiencing technical difficulties within several major services on the platform.
Sites that did not shut down completely were experiencing major latency issues or brief up and down periods. Also included was question and answer site Formspring.
Most issues occurred because of three Amazon platform issues; Amazon Elastic Compute Cloud, Amazon Elastic Beanstalk and Amazon Relational Database Service.
All sites affected appear to be working correctly at this time.
