Description
I am using a shutdown script to save a file whenever preemptible VM instances shut down.
I am authed to my project inside the VM through service accounts (cloud), as I have access by simply doing fs = gcsfs.GCSFileSystem() during runtime.
However, at the time when the VM preempties and my shutdown script triggers, I cannot instantiate the filesystem anymore:
Compute Engine Metadata server unavailable on attempt 1 of 3. Reason: timed out..
Does this mean I have lost all internet connectivity, or just some? Would it work to somehow cache my authentication?

Research direction
No files or tests are named. Start by reproducing the reported shutdown behavior around gcsfs.GCSFileSystem() and inspect the Compute Engine metadata authentication path used during VM preemption. Done means the expected authentication behavior during shutdown is established and any necessary handling is covered by a reproducible test.
