It’s the Murphy’s Law corollary for cloud computing: anything that can go wrong will go wrong on the eve of a major holiday.
Amazon’s CloudFront content delivery network is suffering from DNS problems worldwide, which means some users are having a hard time connecting to web services that count on CloudFront to deliver their content. According to reports on Twitter, people are having problems with sites like Medium and Instagram, though it’s hard to tell just how widespread the issues are.
According to the AWS service status page, Amazon is looking into the problems and is working on a fix as of 5 p.m. PST tonight. The outage began around 4:15.
Update: CloudFront is up and running normally as of 6:02 p.m. PST tonight, according to the AWS service status page.
This problem is reminiscent of Amazon Web Services’ Elastic Load Balancer failure from Christmas Eve 2012, which notably knocked out Netflix service right as families were sitting down to some holiday entertainment. Right now, it’s unclear exactly how widespread the DNS problems are, or if they’ll have anywhere near the same effects on Amazon’s customers.
