Lokalise application is unavailable

On January 26, 2026, Lokalise experienced a service outage and performance degradation between 15:52 UTC and 16:32 UTC. During this time, the Lokalise application was unavailable, and users of the API experienced intermittent connectivity and high latency.

What happened?

The Cause: The incident was triggered during a migration of our monitoring systems. A configuration mismatch caused a high volume of internal network requests to fail, which subsequently overwhelmed our internal DNS services. This prevented various parts of our infrastructure from communicating with one another, including our primary databases and application services.

The Fix: Our engineering team identified the source of the traffic and disabled the legacy monitoring configuration. We also rotated affected infrastructure nodes and adjusted our service scaling to alleviate pressure on our databases. These actions restored normal communication between our services, bringing the platform back to full operational status.

Timeline (UTC):

• 15:52: Service degradation and unavailability detected and investigation initiated.
• 16:24: Root cause identified as internal network congestion impacting service connectivity.
• 16:27: Corrective actions implemented; service begins to stabilize.
• 16:32: Full service restored and performance monitored for stability.

What we are doing to prevent this in the future

• Enhancing scaling capabilities: We are upgrading our internal DNS services to scale horizontally, ensuring they can handle unexpected spikes in traffic without impacting the wider platform.
• Improving resource monitoring: We are implementing additional alerting for resource exhaustion to identify and mitigate infrastructure bottlenecks before they impact service availability.
• Refining deployment procedures: We are updating our internal documentation and validation steps to ensure infrastructure dependencies are strictly coordinated during system migrations.

We sincerely apologize for the disruption this incident caused to your workflow. We understand how critical Lokalise is to your operations and are committed to improving our system's resilience to prevent a recurrence.
