Hi there, I was in the middle of updating the SKU of my Azure Cache for Redis instance with Terraform when the process crashed. Now, the Redis instance is stuck in a scaling/update state, and it hasn't moved forward for a while. I'm looking for advice on how to safely stop or cancel this operation, as it's creating a blockage on my end. Update: It's been four hours, and now it's showing that the scaling has failed and the cache is in a failed state. What can I do to bring it back to a running state?

If the CLI isn’t deactivated, trying it to stop the operation could work— I found that helpful when portal options are limited.
There's a reboot option in the portal under Administration. But I'm not sure if it will help with an ongoing scaling task. Just be cautious with it; you don’t want to break anything.
I recommend opening a Microsoft support ticket. They can assist with issues like this, and if needed, escalate your case for a quicker resolution.
You can also try to use resources.azure.com to clear this issue, but I’ve heard it might be retired soon. If it still works, it’s worth a shot.
You might want to consider creating a new Azure Redis instance since it’s primarily for caching. Just point your applications to the new one. Also, it could be a good time to look into immutable infrastructure practices.
