## Updates from SerpApi
### 2026-05-21 01:34 UTC: investigating
We are currently investigating an issue affecting the Google Flights API where searches using the \`deep\_search\` parameter may timeout. At this time, the issue appears to impact the majority of requests made with this parameter enabled.
Public Roadmap:
https://github.com/serpapi/public-roadmap/issues/2749
As a temporary workaround, we recommend omitting the \`deep\_search\` parameter.
We apologize for the inconvenience and appreciate your patience while we work on a fix.

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