Traffic Impacted for VPC Endpoints

2:18 PM PST We are investigating connectivity issues affecting VPCE PrivateLink Endpoints in a single Availability Zone (use1-az1) in the US-EAST-1 Region.

3:17 PM PST We wanted to provide you with some more details on the periods of network connectivity issues for VPCE Private Link within a single Availability Zone (use1-az1) within the US-EAST-1 Region. While we are currently not observing any network connectivity issues at this moment, we did observe two periods of impact, the first between 11:30 AM and 12:00 PM PST and the second between 1:00 PM and 1:45 PM PST. We have identified the subsystem that was responsible for this issue but continue to work towards identifying root cause and mitigating any further impact. We will continue to provide updates on our progress towards full recovery, and immediately should the network connectivity issues return.

3:59 PM PST We continue to investigate root cause of the issue affecting network connectivity for PrivateLink within a single Availability Zone (use1-az1) in the US-EAST-1 Region. We have not seen impact since 1:45 PM PST and our engineering teams remain engaged as we work to determine root cause, and apply mitigations before resolving this event. Since this issue only affected a single Availability Zone, customers who are able to route network traffic through alternative Availability Zones for the affected services, should consider doing so.

4:33 PM PST We have not seen any further network connectivity issues for PrivateLink since 1:45 PM PST. We have also identified the root cause and prepared a fix to address the issue. The engineering team is currently working on testing this fix and preparing for deployment to the affected subset of hosts that were affected by this issue. We will continue to provide updates as we work through that deployment.

5:37 PM PST We have seen no further network connectivity issues for PrivateLink since 1:45 PM PST (5 hours ago). We have identified the root cause and prepared a fix to resolve the issue, which is now being deployed. We have also taken steps to mitigate any impact should the issue reoccur before the deployment is fully completed. This issue resulted in two periods of network connectivity issues between 11:30 AM and 12:00 PM PST, and between 1:00 PM and 1:45 PM PST. The issue has been resolved and the service is operating normally.
