-# Can't Set `regions` and `scale` Options Simultaneously
-
-#### Why This Error Occurred
-
-Your deployment's configuration contains a `regions` and `scale`
-configuration simultaneously.
-
-#### Possible Ways to Fix It
-
-The `regions` setting is intended to be used to scale the
-deployment to the supplied regions or datacenters identifiers
-with default scale settings.
-
-```json
-{
-  "regions": ["sfo", "bru", "gru", "iad"]
-}
-```
-
-The `scale` object allows you to be more granular: you can decide a
-`min` and `max` number of instances per region:
-
-```json
-{
-  "scale": {
-    "sfo": { "min": 0, "max": 10 }
-  }
-}
-```
-
-To solve this problem, use only one of the two ways of deciding
-where to scale your deployment to.

-# `vercel scale ls` is deprecated
-
-#### Why This Error Occurred
-
-We have stopped supporting this command, in favor of
-better alternatives.
-
-`vercel scale ls` used to list all the scaling rules
-for all your deployments. The output would be too long,
-and it would often be hard to find the information
-you needed in a long list of items.
-
-#### Possible Ways to Fix It
-
-Instead of using `vercel scale ls` to list all your deployments
-and their scaling rules, first use `vercel ls` to find
-your deployment:
-
-```console
-vercel ls
-```
-
-Then, select the URL of your deployment, which uniquely identifies it, and run:
-
-```console
-vercel inspect my-deployment-12345.now.sh
-```
-
-The `inspect` subcommand will give you your deployment's scale information, including what datacenters it's enabled on, the
-current number of instances and minimums/maximums.

-You tried to use `vercel scale` on a path alias (`vercel alias -r rules.json`).

-
-Path aliases are routes to instances. Instances can be scaled independent from each other.

-An attempt was made at scaling a Cloud v2 deployment with a `min` scale

-#### Possible Ways to Fix It
-
-Ensure your scale settings (in `vercel.json`, the command you're running

-the `min` scale setting set to `0`. You can do this by running

-# Verification Timeout
-
-#### Why This Error Occurred
-
-After the deployment build completed and the deployment state was set to `READY`,
-instances failed to initialize properly.
-
-The CLI attempted to verify that the scale settings of your instances matched,
-but it couldn't do so within the allotted time (defaults to 2 minutes).
-
-#### Possible Ways to Fix It
-
-Instance verification is the process of ensuring that after
-your deployment is ready, we can actually run (instantiate) your code.
-
-If you configured [regions or scale](https://vercel.com/docs/features/scaling),
-we ensure the minimums and maximums are met for the regions you enabled.
-
-If you think your code is taking too long to instantiate, this can be due
-to slow boot up times. You can supply `--no-verify` to skip verification
-if you are confident your code runs properly.
-
-If your application is not listening on a HTTP port, we might be failing to
-instantiate your deployment as well. It might not be showing any errors,
-but the deployment instance is effectively not routable and cannot be
-verified.
-
-If your instances are crashing before an HTTP port is exposed, verification
-will fail as well. Double check your logs (e.g.: by running `vercel logs <url>`)
