Is there any contingency plan for an agent to continue running a task without reading the repository on the GitLab server?

Not sure what can be done ... any suggestions ?

At runtime, can I ask the agent to use some cached repository?

sometimes you will have it (as the agent stores a cached copy, but I would hardly count on it (and it might be at different states on different machines...)

... (due to regular maintenance service, something I cannot control).

Maybe let "them" know that CI/CD processes actually count on Git being available ? 🤔
