What happened
On Sep 8, 2025 at 09:59 UTC, a change introduced in our system unexpectedly missed a Feature Toggle condition, which caused a spike in the number of requests to one of our internal services. This led to degraded performance and temporary unavailability of both the Lokalise App and API. Our monitoring and alerting systems immediately triggered the alerts, allowing us to quickly identify and restore the service.
Impact
The Lokalise App was unavailable for approximately 9 minutes, and the API experienced downtime for about 6 minutes within that window. No customer data was lost or corrupted.
What we are doing to prevent this in the future
We are implementing stricter safeguards around feature rollout validation, improving how our services handle spikes in traffic, and adding additional error handling to reduce the risk of cascading failures.
We sincerely apologize for the disruption this caused. Thank you for your patience and continued trust in Lokalise. If you have any questions, feel free to contact us at support@lokalise.com.
