To ensure that the Actions runners are truly ephemeral and more secure, we are now limiting execution timeouts on self hosted jobs to 5 days. If a job reaches this limit, the job is terminated and fails to complete.
GitHub Actions asks customers to review their network allow list for self-hosted runners according to the requirements in our documentation.
Network access to GitHub's *.actions.githubusercontent.com is essential for the self-hosted runners. Requiring wildcard access allows GitHub Actions to be flexible moving forward as we improve the service. Customers that do not allow wildcard access risk having interruptions in their GitHub Actions usage as we start enforcing this requirement on September 12, 2023. Please reach out to the customer support if you have limitations with configuring wildcard access in the on-premises firewall solution.
