Description
Increased API Error Rates
[10:43 PM PDT] We are investigating increased API error rates for the EC2 APIs in the AP-EAST-1 Region.
[10:51 PM PDT] We can confirm increased error rates for the EC2 APIs and degraded performance for some EBS volumes within a single Availability Zone within the AP-EAST-1 Region
[11:08 PM PDT] We continue to investigate increased error rates for the EC2 APIs, degraded performance for some EBS volumes and EC2 instance connectivity issues within a single Availability Zone (ape1-az2) in the AP-EAST-1 Region. Other Availability Zones within the AP-EAST-1 Region are not affected by this event.
[11:27 PM PDT] We continue to investigate increased error rates for the EC2 APIs, degraded performance for some EBS volumes and EC2 instance connectivity issues within a single Availability Zone (ape1-az2) in the AP-EAST-1 Region. We are making progress towards determining root cause for this event, but have not been able to determine it at this stage. Since other Availability Zones within the AP-EAST-1 Region are not affected by this event, we recommend that you fail away from the affected Availability Zone.
[12:03 AM PDT] We continue to investigate increased error rates for the EC2 APIs, degraded performance for some EBS volumes and EC2 instance connectivity issues within a single Availability Zone (ape1-az2) in the AP-EAST-1 Region. We are making progress in determining the root cause and believe it is related to communication between EC2 instances and attached EBS volumes. This leads to degraded performance for affected EBS volumes within the Availability Zone and can also lead to impaired EC2 instances due to stuck IO within the operating system. While we continue to work towards resolving the issue, we recommend that you fail away from the affected Availability Zone if you have not already done so. |
