Summary and Steps to reproduce

Important note: these bugs have taken place after the "current blackout" and Idiap networking services restore

When trying to push to beat.editor some commits I now get two errors :

[INFO] Installing environment for https://github.com/ambv/black.
[INFO] Once installed this environment will be reused.
[INFO] This may take a few minutes...
An unexpected error has occurred: CalledProcessError: Command: ('/home/neo/miniconda3/envs/beat_editor_v2/bin/python', '-mvirtualenv', '/home/neo/.cache/pre-commit/repos__f8_6t/py_env-python3.7', '-p', 'python3.7')

So I thought ok I maybe need to update python on my conda environment:

When I do a conda install python=3.7 I then get:

CondaHTTPError: HTTP 503 SERVICE UNAVAILABLE for url <https://www.idiap.ch/software/beat/conda/label/beta/linux-64/repodata.json>
Elapsed: 00:03.326174

A remote server error occurred when trying to retrieve this URL.

A 500-type error (e.g. 500, 501, 502, 503, etc.) indicates the server failed to
fulfill a valid request.  The problem may be spurious, and will resolve itself if you
try your request again.  If the problem persists, consider notifying the maintainer
of the remote server.
