Hi @Derek Hu,
Yes, the Azure Active Directory Authentication Library (ADAL) for JavaScript version 1.0.16 is still accessible via the CDN URL you provided:
https://secure.aadcdn.microsoftonline-p.com/lib/1.0.16/js/adal.min.js
However, it's important to note that ADAL has been deprecated. Microsoft officially ended support for ADAL on June 30, 2023. This means no new features or security updates will be provided for ADAL. While existing applications using ADAL will continue to function, it's strongly recommended to migrate to the Microsoft Authentication Library (MSAL) to ensure continued support and enhanced security features. https://learn.microsoft.com/en-us/entra/identity-platform/msal-migration

For new projects or when updating existing applications, consider transitioning to MSAL.js. MSAL offers improved security, supports the Microsoft identity platform (v2.0), and provides a more robust and flexible authentication experience. https://github.com/AzureAD/azure-activedirectory-library-for-js?
