Webhooks and event streams partial data loss
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.

Asana·Asana downtime
**Incident:** An infrastructure update targeting security caused DynamoDB to become inaccessible across Asana's production environment. This change was related to a production isolation initiative, and was applied in a way that left all of our production services unable to use DynamoDB tables which we use for metadata and routing traffic. Once the change was reverted our services returned to normal operations. **Impact:** Asana services were completely unavailable for approximately 30 minutes, 2026-10-21 15:21 UTC-15:51 UTC, and mostly unavailable for a further 20 minutes, including 15:05 UTC-15:55 UTC. This also caused delay for background actions during the impact period; recovery after the end of the incident completed by 16:00 UTC. **Moving forward:** We are updating the deployment process to catch this class of error. We will be moving to an isolation system which allows more gradual rollout of similar changes, allowing us to detect misconfiguration in pre-production testing. Our

Your coding agent knows when Asana is down, and tells you when a failure is theirs, not yours. You can also get Asana incidents in a feed reader or in Slack.
Install the outages.live MCP server, so that when something breaks you can tell if the cause is a provider we depend on and not my code. It reads the official status pages of cloud, AI, payment and developer providers and gives you their incidents as MCP tools.
Add it as a remote MCP server named "outages" at https://outages.cc/mcp (Streamable HTTP, no authentication), with your CLI command or your MCP config file.
Then:
1. Make sure it connects and shows the tools get_provider, list_feed and send_feedback.
2. Call get_provider with "asana" and tell me if Asana has a problem right now.
3. From now on, when a call to a third-party service fails or becomes slow, call get_provider for that service before you change my code.Paste this into any coding agent. It adds the server with its own MCP setup.
