Thanks for your reply!

The info you asked for:

```bash
$ fly autoscale show
     Scale Mode: Balanced
      Min Count: 1
      Max Count: 8

```

```bash
$ fly scale show
VM Resources for uptime-monitor-backend
        VM Size: shared-cpu-1x
      VM Memory: 256 MB
          Count: 1
 Max Per Region: Not set

```

```bash
$ fly releases

For `burn`, I’ve most recently used `./burn -c 400 -d 120s https://uptime-monitor-backend.fly.dev/ --verbose --resume-tls`.  
Maybe two minutes is not long enough for autoscaling to kick in?

I have also recently (on another app, but with a similar setup) tried to use `locust`, scaling the number of users up to 600 by adding 2 more per second (e.g. reaching the peak after ten minutes, although the `soft_limit` would be passed after the first ten seconds), with similarly no autoscaling happening.

I have tried both `type = "connections"` and `type = "requests"`.

The topic you pointed to ([this one](https://community.fly.io/t/how-long-does-it-take-for-autoscaling-to-take-effect/3245/2)) did not actually seem to mention anywhere how much time is taken for autoscaling to kick in.  
I did find [this post by @kurt](https://community.fly.io/t/autoscale-doesnt-seem-to-launch-new-instances/2559/3) mentioning “it needs to be maxed out 30-60s”. But maybe that information is outdated?
