We are celebrating the Berkeley Institute for Data Science as our first premier member! Join us at UC Berkeley on Oct 15th (tomorrow!) to discuss and celebrate. Event details here 👉 events.berkeley.edu/BIDS/event/3...

mybinder.org recently hit some port scanning abuse issues. We helped create tcpflowkiller to detect & stop port scanning for BinderHub! This will benefit each of the BinderHub federation member instances. Learn more 👉 2i2c.org/blog/2025/my...

💡 TIL: GitHub Actions secrets become empty strings in a PR from a forked repository. Apparently it's a security feature, not a bug! We learned this the hard way and wrote up our learnings in case it's helpful to others 👉 2i2c.org/blog/2025/gi...

Our collaborators at OpenScapes are hiring! Looking for someone with open science experience to work with NASA suborbital teams on reproducible notebooks and teaching. Fully remote 👉 openscapes.org/connect#work...

We're giving our communities more transparency into their cloud expenses with new cloud cost dashboards! Communities can track spending at a per-user level to understand who is driving their usage and take action. Learn more 👉 2i2c.org/blog/2025/cl...

How should organizations support open source communities? We're moving from scattered individual efforts to strategic team-based contributions that strengthen upstream communities like JupyterHub 🚀 👉 2i2c.org/blog/2025/fo...

We're making our cloud infrastructure more transparent! 2i2c just launched a status page to give our research and education communities real-time visibility into the reliability of their JupyterHub infrastructure. Check it out 👉 2i2c.org/blog/2025/st... Status page 👉 status.2i2c.org

Leadership in open source is hard to track, but it's critical! As part of 2i2c's Foundational contributions to open source, Chris is serving on the Jupyter Executive Council. We're documenting his efforts here to provide transparency: 👉 2i2c.org/blog/2025/ex...

We reduced AWS infrastructure costs for communities by switching from older `r5.xlarge` to newer `r8i-flex.large` instances for our "always-on" hub infrastructure. It's a good day when we save cloud costs for our communities ✨ Learn more 👉 2i2c.org/blog/2025/aw...

As part of our experiment in doing more of our work in the open, we're going to post summaries of our incident reports as they happen. Here's a recent one during a login surge for a classroom: 2i2c.org/blog/2025/in...

Open practices means open communication. We're running an experiment to share more of our learning, experiments, and contributions in real-time rather than waiting for polished outcomes. Here's a little post describing this effort 👉 2i2c.org/blog/2025/co...

How should an organization support open source? A key goal for 2i2c is to lead by example in contributing to a healthy open source ecosystem. We've learned a lot over the years - here's our framework for building healthy open source relationships. 👉 2i2c.org/blog/2025/go...

A reminder that tickets are now available for JupyterCon 2025! Schedule and agenda here 👉 events.linuxfoundation.org/jupytercon/p... Conference website here 👉 events.linuxfoundation.org/jupytercon/

A reminder that there are two Call for Proposals out from the Jupyter Foundation! 👉 (extended deadline!) Jupyter Community Workshops: blog.jupyter.org/jupyter-comm... 👉 Jupyter Community Support funding: blog.jupyter.org/your-ideas-o... Check them out and share the word!

Our technical lead Yuvi recently shared the JupyterHub team's interest in expanding beyond Jupyter Notebooks to enabling more flexible applications on hosted infrastructure. Learn more about his talk for doepy 👉 2i2c.org/blog/2025/do... Video here 👉 www.youtube.com/watch?v=vsbH...

Documentation doesn't get enough love these days! We're heavy users of the repo2docker tool for user environment generation for our communities. Chris recently spent a bit of time updating repo2dockers documentation, and wrote up an experience report about it. Thanks Chris! 2i2c.org/blog/2025/re...

Each quarter, our team checks in on what we've released, how we've improved as an organization, and what's coming next for members of our community network. What we've been up to: 2i2c.org/blog/2025/q2...

Our Product team gets a unique view across science and education communities. That perspective means we're able to solve classes of problems, in ways that benefit all the communities we serve. Yuvi, our Tech Lead, shares what happened when we noticed autoscaling problems: 2i2c.org/blog/2025/au...

CIROH's Research Cyberinfrastructure and DevOps team shared their experience and methods from their recent DevCon - check it out for inspiration: docs.ciroh.org/blog/devcon2... Congratulations to the team on a successful conference! It was a pleasure collaborating with you!

We're addressing feedback on the challenges of managing user groups in JupyterHub by introducing new group management features to track resource usage efficiently. By integrating insights from Prometheus and Grafana, communities can better manage complex, dynamic user bases: 2i2c.org/blog/2025/ju...

Early this year, we started to explore Jetstream2 on behalf of our NSF-supported communities. We're happy to report that 2i2c is now able to deploy both mybinder.org-like hubs as well as persistent storage hubs on Jetstream2 hardware! More on our blog:

Openscapes, partnering with NASA, NOAA and 2i2c, hosted a community call in April 2025 to share learnings about managing cloud costs for earth sciences. Check out the blog post, including the community call recording and notes: openscapes.org/blog/2025-05...

We've launched Jupyter Book for 2i2c communities! With Jupyter Book 2, communities can focus more on content than design, with improved interactive environment launches from Jupyter Book, added features for landing pages, and colocated community documentation with hubs.

Three of our user communities put 2i2c infrastructure to work making research and education more accessible, and they shared their experiences in the March 2025 Oceanography magazine: tos.org/oceanography.... Recap and links in our blog: 2i2c.org/blog/2025/ha...

We're proud to announce that our Executive Director, Chris Holdgraf, was elected to the Jupyter Project's Executive Council! We excited for the impact that he'll have in this strategic role!

We're exploring ways to support scientific reproducibility and sustainability with Binder. What if we could reduce the gap between where researchers conduct their computational analyses using open source technologies and bridge them to publishing platforms for dissemination?

2i2c has officially become part of the mybinder.org federation, introducing a new, cost-effective, and faster approach. We hope to make it easier for more people to join the federation by contributing a single-node BinderHub at 2i2c.mybinder.org. More in our blog: https://2i2c.org/blog/2025/binde…

We have just shipped a solution for managing storage quotas in JupyterHub with @developmentseed.org 🚀 No more worrying about users filling up shared storage space. Check out our blog post for more: https://2i2c.org/blog/2025/per-user-storage-quota/

As 2024 draws to an end, we’re excited to share our retrospective and impact report. We’re incredibly proud of the work that 2i2c and our community network have done in 2024, and would love to hear your feedback for where should go next in 2025. : 2i2c.org/blog/2024/re...
