@leo-singer I see that you have created a new branch in your repo to get rid of the branch in the origin. What would my role be here? It seems like the pipeline is failing right now. Are you working on it?

@shaon.ghosh, the branch is still ready to merge as soon as the VOEvent support arrives in GraceDb and GWCelery. Nothing you need to do; I just attached you to the merge request to document that it's your contribution.

The CI is failing because a new version of Astropy was released today and the rollout on PyPI is only halfway done. That should resolve itself soon.
