Uploading errors in Asset Manager

Incident Report for imgix

Postmortem

Summary

Between 2026-01-09 21:26 UTC and 2026-01-12 14:18 UTC, some asset uploads returned an upload failure error in Asset Manager despite the uploads completing successfully.

Additionally, legacy video customers experienced transcoding delays as a result of the incident.

What Went Wrong

A production misconfiguration caused a validation step in the Asset Manager pipeline to fail.

As a result:

The legacy video encoding process did not initiate for uploaded videos
Assets did not appear in Asset Manager because they failed validation

While affected assets were still available at the origin and accessible via the Rendering and Video APIs, they did not appear in the Asset Manager UI and were not available through the legacy Long-Form Video API.

What we will do to prevent this in the future

We have done the following things:

Added more alerting and patched logging gaps to catch the issue sooner
Fix a flaw in our build system that allowed a two-step deploy to get out of sync

Investigating

We are investigating an issue where Asset Manager returns errors for uploaded assets. Affected assets can still be served through the Rendering API but will not be visible in Asset Manager.

Customers using the legacy Long Form Video feature may also encounter video delivery errors.

We are investigating this issue.
