_Describe your question/issue here! (delete this when you post)_

In my project I’m using the hosted API to run inference on my workflow which is a quite standard Yolo SAHI flow. Usually the inference is stable without issues, but the other day all of a sudden I keep getting timeouts in my attempts to run inference. This also happened sometimes when testing the workflow through [app.roboflow.com](http://app.roboflow.com)

The error I see is this:

```auto
> {"severity":"WARNING","message":"TypeError: fetch failed\n at node:internal/deps/undici/undici:12618:11\n at process.processTicksAndRejections (node:internal/process/task_queues:95:5)\n at async makeRequest (/functions/lib/detector/utils.js:81:30) {\n cause: ConnectTimeoutError: Connect Timeout Error\n at onConnectTimeout (node:internal/deps/undici/undici:7760:28)\n at node:internal/deps/undici/undici:7716:50\n at Immediate._onImmediate (node:internal/deps/undici/undici:7748:13)\n at process.processImmediate (node:internal/timers:478:21) {\n code: 'UND_ERR_CONNECT_TIMEOUT'\n }\n}"}
> {"severity":"ERROR","message":"Unhandled error TypeError: fetch failed\n at node:internal/deps/undici/undici:12618:11\n at process.processTicksAndRejections (node:internal/process/task_queues:95:5)\n at async makeRequest (/functions/lib/detector/utils.js:81:30) {\n cause: ConnectTimeoutError: Connect Timeout Error\n at onConnectTimeout (node:internal/deps/undici/undici:7760:28)\n at node:internal/deps/undici/undici:7716:50\n at Immediate._onImmediate (node:internal/deps/undici/undici:7748:13)\n at process.processImmediate (node:internal/timers:478:21) {\n code: 'UND_ERR_CONNECT_TIMEOUT'\n }\n}"}

```

My questionsa:

1. Is there something that can be done to mitigate these issues with the hosted inference?
2. Do you have some kind of “downdetector” that I can use in my project to detect if there are issues with the API?
3. Do you have some mirrors for the hosted API if these failures are common during a certain period?

Thanks

Thanks for writing in @agoransson. Are you still running into issues? We recently experienced a few unusual delays as a result of an upstream provider.

Right now I’m seeing issues again, but it’s not noted on the [status.roboflow.com](http://status.roboflow.com) website.

Worth mentioning is that I’m using the [serverless.roboflow.com](http://serverless.roboflow.com) server.

Thanks
