Update timeline
- investigating Jul 06, 2026, 10:49 AM UTC
We are investigating an issue with PowerSync in the US region where new processes may fail to provision. This affects instance deploys, as well as auto-scaling on existing deploys.
- monitoring Jul 06, 2026, 12:00 PM UTC
We have identified the issue and applied a workaround. An upstream outage at AWS in our US region prevented our auto-scaling infrastructure from provisioning new EC2 nodes. This caused overall capacity to be too low, affecting instance deploys, instance scaling, and some existing instances. We have applied a workaround to manually scale our capacity, which addresses the issue in the short term. We are working with AWS to resolve the underlying issue, while continuing to monitor the capacity.
- resolved Jul 06, 2026, 03:30 PM UTC
AWS has resolved the underlying issue. We are back on our standard auto-scaling infrastructure, and everything is operating normally.
