Arcade.dev incident

Unplanned Downtime

Resolved after 33 minutes, affecting Engine API, on November 6, 2025.

resolved Nov 06, 2025, 11:54 PM UTC

We determined that because of recently adding thousands(!) of tools, one of our production components required a longer than expected startup process, meaning its health check endpoint was unavailable before the timeout expired. As a result, orchestrator was constantly restarting nodes, leading to poor availability of this critical component. Going forward, we plan to move these tasks out of component startup so this doesn't happen again and we can continue to support even larger numbers of tools.
