On Sunday afternoon, Amazon Web Services reported degraded performance for its EC2 service in Northern Virginia, as well as connectivity issues for load balancers in the same region.
The issues lasted about an hour, and Amazon promptly diagnosed the causes of the problems.
“We have identified and fixed the root cause of the connectivity issue affecting load balancers in a single availability zone,” an update on the AWS status dashboard at 2:45 pm PT said. “The connectivity impact has been mitigated for load balancers with back-end instances in multiple availability zones. We continue to work on load balancers that are still seeing connectivity issues.”
The problems impacted customers’ of AWS users Instagram and Vine, and according to TechCrunch, Netflix, IFTTT, Heroku and Airbnb all experienced issues with performance related to the AWS problems.
Last week, the homepage of Amazon.com suffered an outage that lasted nearly an hour. The outage didn’t impact AWS users.
Amazon’s uptime is 99.95 percent and while it usually is very communicative and transparent with customers, any downtime it has is magnified due to the size of its user base as well as the nature of the apps its clients’ hosts. Instagram for example has 130 million active monthly users, while this week, Vine topped 40 million registered users.
