Due to system migration works, the present CPAS platform will be unavailable starting 25 July 2025. Users are advised not to make new subscription nor submit any new job before the new CPAS platform is available. If you have temporary job result data or files in the Jupyterhub system in the current platform, please access them before 25 July 2025.
We are sorry for short notice time. If you have any inquiries, please kindly email enquiry@cpas.earth.
(Users with active paid subscription will be notified individually, in addition to this system notice)

There is a plan that by 8 Aug 2025, the Jupyterhub visualization system hosted by the CPAS platform itself will be terminated. A new mechanism that supports users to leverage their own or third party Jupyter notebook / lab resources, yet being able to access CPAS Mesh Generation and Real Simulation job results, would be set up.
If you would like to back up your files (mainly your .ipynb files and generated figures, etc.) saved in https://vis.cpas.earth/, please do so before the above date.
