+### Codespace creation fails
+
+If the creation of a codespace fails, it's likely to be due to a temporary infrastructure issue in the cloud - for example, a problem provisioning a virtual machine for the codespace. A less common reason for failure is if it takes longer than an hour to build the container. In this case, the build is cancelled and codespace creation will fail.

+
+**Note:** A codespace that was not successfully created is never going to be usable and should be deleted. For more information, see "[Deleting a codespace](/codespaces/developing-in-codespaces/deleting-a-codespace)."

+
+If you create a codespace and the creation fails:
+
+1. Check {% data variables.product.prodname_dotcom %}'s [Status page](https://githubstatus.com) for any active incidents.
+1. Go to [your {% data variables.product.prodname_github_codespaces %} page](https://github.com/codespaces), delete the codespace, and create a new codespace.
+1. If the container is building, look at the logs that are streaming and make sure the build is not stuck. A container build that takes longer than one hour will be canceled, resulting in a failed creation.
+
+   One common scenario where this could happen is if you have a script running that is prompting for user input and waiting for an answer. If this is the case, remove the interactive prompt so that the build can complete non-interactively.

+2. If you have a container that takes a long time to build, consider using prebuilds to speed up codespace creations. For more information, see "[Configuring prebuilds](/codespaces/prebuilding-your-codespaces/configuring-prebuilds#configuring-a-prebuild)."

 ## Deleting codespaces
 
 The owner of a codespace has full control over it and only they can delete their codespaces. You cannot delete a codespace created by another user.
