Hi,
First of all many thanks for providing this service, this is excellent!
We want to use it for an educational course and have been testing it for some time and it worked really now.
However, just an hour ago it stopped building (it gets stuck there for quite some time).
According to the status page it seems to be working?
Note: I can build the docker container using `repo2docker` locally.
Many thanks.
Hi @Kaustubh_Patil,
Thanks for the message. We had to test a hypothesis, see Launch get stuck in building phase after write to registry · Issue #3387 · jupyterhub/mybinder.org-deploy · GitHub and Revert "Downgrade Docker dind from 28.3.3-dind to 27.5.1-dind" by rgaiacs · Pull Request #3428 · jupyterhub/mybinder.org-deploy · GitHub.
Your message is very valuable to us. I need another 2-4 hours to follow up and I will probably revert the change.
Dear Raniere
Many thanks for the info.
This comes at an unfortunate time for us because we were planning on using this service at this moment 
Best regards

Dear Kaustubh,
https://mybinder.org/ sends the requests to two servers https://2i2c.mybinder.org/ and https://gesis.mybinder.org/. I noticed that https://2i2c.mybinder.org/ is having problems with the build but builds at https://gesis.mybinder.org/ are working as expected.
Dear Kaustubh,
Changes to mybinder.org were revert. Let us know if you encounter any problem.
