Between 9:42 AM and 11:44 AM PDT, we experienced elevated network packet loss impacting AWS Direct Connect connectivity in the AP-SOUTH-1 Region. Our engineering team was automatically engaged at 9:46 AM to begin investigating. By 10:51 AM, we understood the root cause to be a configuration change made to a system responsible for assigning routes to devices. As we gained confidence in our mitigati…
We have identified the root cause to be related to a change made to a configuration system responsible for assigning routes to the devices. We have begun the work to reduce the packet loss that is impacting AWS Direct Connect in the AP-SOUTH-1 Region, and we expect recovery to take place gradually over the next 30 minutes. As we gain confidence in these efforts, we will seek to parallelize our eff…
We can confirm elevated network packet loss, impacting AWS Direct Connect connectivity in AP-SOUTH-1 Region. Our engineering team was automatically engaged at 9:54 AM to begin investigating the issue. There are no workarounds available at this time. We will provide another update by 11:30 AM PDT.
Between 3:55 AM and 4:15 AM PDT, we experienced connectivity issues that impacted connectivity to the US-WEST-2 Region. This impacted multiple AWS services in the Region. Some customers may have also experienced issues accessing the AWS Management Console, with connection timeouts and unresponsive pages. Connectivity within the Region was not affected. Our engineers were automatically engaged at 4…
We continue to see significant signs of recovery as a result of our mitigation efforts for the connectivity issues impacting multiple AWS services in the US-WEST-2 Region. We have identified the root cause as an issue with a networking device responsible for network routing from the Region to the Seattle Metro. Engineers have finished all mitigation work. As routes continue to be restored, custome…
We are seeing initial signs of recovery and continue to work toward full recovery.

Between July 16 at 7:38 PM PDT and July 17 at 6:00 AM PDT, customers received erroneous budget and cost anomaly detection alerts, and saw inflated estimated cost and usage data in the Billing and Cost Management Console and the Cost and Usage Reports. These inaccurate billing estimates did not affect customer invoices. On July 16, 2026 at 7:46 PM PDT, our alarms detected cost anomalies but failed…
We continue to make substantial progress toward resolving the issue affecting estimated cost and usage data displayed in the Billing and Cost Management Console. Our mitigation efforts are working as expected and we are seeing an increasing number of accounts reflecting correct cost and usage data. We expect all affected accounts to be fully recovered by July 19, 12:00 AM PDT. Until the backfill i…
We continue to make steady progress toward resolving the issue affecting estimated cost and usage data displayed in the Billing and Cost Management Console. Our efforts to backfill corrected data remain underway, and we expect all affected accounts to be fully recovered by July 19, 12:00 AM PDT. Until the backfill is complete, some customers may still observe incorrect cost and usage data in the B…
Our efforts to backfill corrected estimated cost and usage data are still underway. We are progressing slower than anticipated. While we are seeing some accounts recover with correct cost and usage data, we expect all affected accounts to be recovered by July 19 12:00 AM PDT. Until the backfill is complete, some customers may still see incorrect cost and usage data. The displayed billing estimates…
We have identified the root cause and mitigated the underlying issue causing incorrect estimated cost and usage data to be displayed in the Billing and Cost Management Console, and Cost and Usage Reports. We have begun backfilling data to correct cost data for all customers. We expect some customers to begin seeing recovery within the next three hours, and full recovery for all customers by July 1…
We continue to work to resolve the issue affecting estimated cost and usage data displayed in the Billing and Cost Management Console, including the Cost and Usage Report. The rollback of a recent change did not resolve the issue and we are continuing to investigate multiple mitigation paths. Estimated bill updates remain paused. We are in the process of reverting to the last accurate estimated bi…
We continue to work on multiple mitigation paths in parallel to resolve the issue affecting estimated cost and usage data displayed in the Billing and Cost Management Console. We are evaluating resuming estimated billing computations, as our internal monitoring indicates the billing computation subsystem is now producing accurate estimates. We are conducting additional validation before proceeding…
We continue to work to resolve the issue affecting estimated cost and usage data displayed in the Billing and Cost Management Console. We are actively working on multiple mitigation paths in parallel. The first path involves reverting to the last known good estimated bill computation. With this approach, customers will only see cost and usage data through July 15, however the inflated cost data wi…
We continue to work to resolve the issue affecting estimated cost and usage data displayed in the Billing and Cost Management Console. As previously shared, we have identified the root cause as an issue with unit pricing within the estimated billing computation subsystem. To prevent further inaccurate billing estimates from being displayed, we have paused estimated billing computations. Customers…
We continue to work to resolve the issue affecting estimated cost and usage data displayed in the Billing and Cost Management Console. We have identified the root cause as an issue with unit pricing within the estimated billing computation subsystem and we are working on a mitigation. The displayed billing estimates do not reflect actual usage and charges. There are no customer actions required at…
Beginning on July 16 7:38 PM PDT, we began displaying incorrect estimated billing data in the Billing and Cost Management Console. Our engineering teams are engaged and investigating root cause. We will provide another update by 3:00 AM PDT or sooner if more information becomes available.
We are investigating issues with Cost Explorer reflecting inaccurate estimated billing data.
Between 12:45 AM and 4:18 AM PDT, we experienced increased 5xx errors for CloudFront customers utilizing VPC Origins connectivity. Our engineers were automatically engaged and immediately began investigating the root cause. By 2:57 AM PDT, we identified the root cause of the issue as an internal constraint on the fleet that manages connections to private VPC origins. When this constraint was reach…
We continue to see significant signs of recovery as a result of our mitigation efforts, with full recovery expected within the next 45 minutes.
We are seeing initial signs of recovery and continue to work toward full recovery.
We continue working to resolve the increased 5xx errors for CloudFront customers utilizing VPC Origins connectivity. Customers utilizing other origin types remain unaffected by this issue. We have further scoped the issue down to routing table capacity within the packet processing subsystem responsible for routing requests from CloudFront's edge locations to resources within customer VPCs. We have…
We continue working to resolve the increased 5xx errors for CloudFront customers utilizing VPC Origins connectivity. Customers utilizing other origin types remain unaffected by this issue. Based on our investigation, we believe the root cause is related to a packet processing subsystem responsible for routing requests from CloudFront's edge locations to resources within customer VPCs. We continue…
Starting at 12:45 AM PDT, we are experiencing increased 5xx errors for CloudFront customers utilizing VPC Origins connectivity. We have confirmed that customers utilizing other origin types are not impacted by this issue. Our engineers are engaged and are actively working to mitigate impact. As a workaround, customers who do not require VPC Origins can change their origin type to resolve the error…
