AWS suffers cloud problems in Sydney region

Offline data store takes out services for hours.

AWS suffered a lengthy and wide-ranging outage on cloud services operating out of its Sydney region.

Users began to report issues with services at 11.15am AEDT and it took until 5.30pm for the problems to be resolved.

The issues affect services including EC2, elastic load balancing (ELB), relational database service (RDS), AppStream 2.0, ElastiCache, WorkSpaces and Lambda.

“@awscloud EC2 instances are not visible on AWS platform. Error fetching instance data across all accounts in Sydney region,” one user said.

“Sydney AWS EC2 console seems down and deployments are failing saying ‘internal simple workflow issues’,” another user tweeted.

On EC2, AWS said the issue “mainly affects EC2 RunInstances and VPC [Virtual Private Cloud] related API requests."

"A data store used by a subsystem responsible for the configuration of Virtual Private Cloud (VPC) networks is currently offline and the engineering team are working to restore it," the cloud provider said.

"While the investigation into the issue was started immediately, it took us longer to understand the full extent of the issue and determine a path to recovery.

"We determined that the data store needed to be restored to a point before the issue began.

"In order to do this restore, we needed to disable writes."

The cloud provider apologised for the extended outage and the impact it had on a range of large and small Australian organisations.

"We apologise for any inconvenience this event may have caused as we know how critical our services are to our customers," it said.

"We are never satisfied with operational performance of our services that is anything less than perfect, and will do everything we can to learn from this event and drive improvement across our services."
