Incident: AWS infrastructure had an outage affecting core services, which our application depends on, in the Virginia (us-east-1) region. The initial impact to our services is covered by https://status.asana.com/incidents/zfdtyvckl5k2; this covers the second major impact to our services.
Impact: Starting at 2025-10-20 14:58 UTC, our application was down for approximately 10% of our users. By 15:08 UTC the application was completely down for all users We saw some improvement in internal error rates around 17:06 UTC resulting in intermittent availability. We did not see full infrastructure recovery until approximately 19:50 UTC and our traffic fully recovered by 20:29 UTC. This affected all regions because we store some global state and shared application configuration in the Virginia region.
Moving forward: We are working on ways to reduce the impact of single region outages, including for this region, to limit the impact and improve options for recovery.
Our metric considers a weighted average of uptime experienced by users at each data center. The number of minutes of downtime shown reflects this weighted average.
