## Updates from Asana
### 2026-08-04 15:30 UTC: resolved
From 2026-08-04 15:25 UTC until 2026-08-06 03:51 UTC, Asana failed to send some events to registered webhooks and to return them in the event streams API. Apps which rely on this should refetch the underlying data from the Asana API. Existing webhooks and event streams will continue to function, but events from the incident window will not be sent.
Most events with type task and action changed were dropped during this period. Other events are not affected.
The root cause of the incident was traced to a code change which unintentionally dropped change events for most fields on the task type, and the change was reverted.

From the builder: does your app depend on Asana? [Sazabi](https://www.sazabi.com/?utm_source=down-guide&utm_medium=markdown&utm_content=asana) detects problems in your own logs without hand-written monitors, and you can ask it in plain language which errors mention Asana.
