Balena incident

Builder Degraded performance

Resolved after 1 day 20 hours, affecting Application Builder, on March 23, 2026.

postmortem Mar 25, 2026, 03:38 PM UTC

Between March 11 and March 25, some cloud builds experienced intermittent failures with "no such image" errors. The issue was non-deterministic and did not affect all builds. We've identified a likely contributing factor and deployed mitigations that have stabilized build reliability. We're continuing to investigate the underlying cause to prevent recurrence. If you experienced build failures during this window, re-running your build should succeed. We appreciate your patience while we worked through this, and we apologize for the disruption.
