AWS have updated their health event with the following update:

7:01 AM PDT We wanted to provide some more information for the event affecting some instances in a single Availability Zone (euw2-az2) in the EU-WEST-2 Region. Starting at 2:05 AM PDT we experienced power and network connectivity issues for some instances, and degraded performance for some EBS volumes in the affected Availability Zone. As a result of this we also experienced elevated API latencies for some of our APIs, elevated API failure rates on the CreateSnapshot API, and elevated instance launch failure rates in the affected Availability Zone. By 4:50 AM PDT, power and networking connectivity had been restored to the majority of affected instances, and degraded performance for the majority of affected EBS volumes had been resolved. While we will continue to work to recover the remaining instances and volumes, for immediate recovery, we recommend replacing any remaining affected instances or volumes if possible.

AWS has updated their status page with the following:

4:46 AM PDT (12.46pm UK) We have restored connectivity to some of the instances in the affected Availability Zone (euw2-az2), and API latencies and launch failure rates are largely recovered. Access to some EBS volumes in the affected Availability Zone was also affected. We are working to restore connectivity to the remaining affected instances and volumes.

If you continue to be affected, you may fall under the minority of instances and volumes that have not been restored. We will continue to monitor the situation and update you when further information is available.

Thank you for your patience.
