It did solve the issue on binder! |

Nice thanks! I think I saw it at one point and forgot about this. I guess not that many people are clicking on the Binder button and/or maybe they don't know where to complain 😓. While you are here @yuvipanda, what is your quick take on the current Binder status? My personal feeling (not being a regular user), is that it less reliable compared to when Google was giving free credits. I mean don't get me wrong, it's great that Binder exists of course, and I have been very grateful in the past when I was using it as backup for scikit-learn tutorials and courses 🙏 ... I have seen a few times some errors (especially on OVH, GESIS seemed more reliable, but not 100% sure) so you need to click a few times until you actually get a working JupyterLab environment 1, even when the image is already cached ( Full disclosure: I have been putting some effort in using JupyterLite/Pyodide which is nice in some ways (no need for a cloud setup) and very surprising in other ways (it looks like normal Jupyter environment but when it breaks it's not easy to figure out what is going on).

@lesteve the short version is that I'm putting a lot of my personal time back into mybinder as of a few months ago, which I hope helps with some of these. We recently added a new bigger node with a very different methodology, sponsored by 2i2c: https://2i2c.org/blog/2025/binder-singlenode/. OVH is no longer here, but their loss has been more than offset by 2i2c. I'm also working with some other institutions to add more capacity. So yes, I do think it has been unstable for a few years now. But I think and hope it will change radically from now! We have rebuilt the entire frontend now (a modern react app), upgraded the builder to use buildkit (jupyterhub/repo2docker#1402), and a host of other changes are coming. Apologies for all the issues in the past, and hopefully we'll get better now. If you run into issues, please report them on jupyter.zulipchat.com. I monitor things there! I also love jupyterlite, and have a 'binderlite' project somewhere in the back of my head... |

@yuvipanda thanks a lot for the details and all the work you are doing for the ecosystem! Great to hear that Binder should be more stable in the future!
Interesting, I would be curious to know more, don't hesitate to ping me in case you find the time to make progress on this! |
