Dear Users,

As part of our ongoing commitment to enhancing cybersecurity, we have implemented a new security measure – Security Intelligence Filtering. This enhancement is designed to automatically filter and block traffic from our HPC system to known malicious websites and domains on the internet, helping to safeguard our infrastructure and users.

With this implementation, you may experience access restrictions to certain websites or domains that are categorized as potential security risks. This may include some well-known platforms such as Hugging Face.

If you encounter access issues and believe a website or domain has been mistakenly blocked, please do not hesitate to contact our helpdesk via the Service Desk Portal or email us at [email protected]. for further clarification and verification.

Thank you for your cooperation and understanding as we continue to strengthen our security measures.

Warm regards,

The NSCC Team
