URL: https://github.com/apache/arrow/issues/47165
### Describe the bug, including details regarding any error messages,
version, and platform.
Python tests are currently failing on several PRs with the following error:
```
______________________ test_s3_real_aws_region_selection
_______________________
@pytest.mark.s3
def test_s3_real_aws_region_selection():
# Taken from a registry of open S3-hosted datasets
# at https://github.com/awslabs/open-data-registry
fs, path = FileSystem.from_uri('s3://mf-nwp-models/README.txt')
assert fs.region == 'eu-west-1'
with fs.open_input_stream(path) as f:
assert b"Meteo-France Atmospheric models on AWS" in f.read(50)
# Passing an explicit region disables auto-selection
fs, path = FileSystem.from_uri(
's3://mf-nwp-models/README.txt?region=us-east-2')
assert fs.region == 'us-east-2'
# Reading from the wrong region may still work for public buckets...
# Nonexistent bucket (hopefully, otherwise need to fix this test)
with pytest.raises(IOError, match="Bucket '.*' not found"):
> FileSystem.from_uri('s3://x-arrow-nonexistent-bucket')
E Failed: DID NOT RAISE <class 'OSError'>
```
A couple of PRs with the failing tests can be seen here:
-
https://github.com/apache/arrow/actions/runs/16442406168/job/46466089732?pr=46992
-
https://github.com/apache/arrow/actions/runs/16442827721/job/46467424395?pr=47148
I've been able to reproduce locally with `archery docker run ubuntu-python`
This started some minutes ago (it was going on the same PR a couple hours
ago) without any code change being merged.
