1. 22:51Elevated Launch FailuresWe are experiencing elevated launch failures in the US-WEST-2 Region.
2. 23:19Elevated Launch FailuresWe are experiencing elevated launch failures in the US-WEST-2 Region caused by an issue with the EBS service. Services that depend on EBS or EC2 will experience failure rates of their own. We are working to mitigate the issues. We will provide you with another update by 4:00 PM PST or sooner if new information becomes available.
3. 00:08Elevated Launch FailuresWe can confirm EC2 instance launch failures affecting all AZs (usw2-az1, usw2-az2, usw2-az3, usw2-az4) in the US-WEST-2 Region. We have identified the issue to be caused by a subsystem that supports EBS Volumes required during instance launch. Services that instantiate new instances, such as cross-region data copy for DataSync, within the US-WEST-2 Region as either the source or destination are also affected. We recommend that customers do not mutate running instances at this time that would result in the replacement or creation of a new EC2 instance in the Region. Running EC2 instances and a
4. 01:12[RESOLVED] Elevated Launch FailuresBetween 2:35 PM and 4:21 PM PST, we experienced elevated EC2 instance launch failures affecting all AZs (usw2-az1, usw2-az2, usw2-az3, usw2-az4) in the US-WEST-2 Region. EC2 Instance Launches, AWS services that instantiated new instances, as well as services such as DataSync or AWS Backup which require new instances to support data transfers to or from the US-WEST-2 Region were affected. Our engineers were automatically engaged and immediately began investigating the root cause. We identified the issue to be caused by a subsystem that supports EBS Volumes required during instance launch. We be
