Open Stack

Hello team

Does anyone know about why sqlalchemy-utils fails devstack install since about 3:00 UTC, Feb 25th?

Our CI start to fail and in log it says:

2016-02-25 03:34:22.515 | Collecting SQLAlchemy-Utils===0.31.6 (from -c /opt/stack/new/requirements/upper-constraints.txt (line 24))

2016-02-25 03:34:23.062 | Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-build-eRYND2/SQLAlchemy-Utils

However, in mirror[1] which we are using, the package is just there, which confused me.

Thanks for any help.
