Materials Project website stuck on homepage while URL changes normally

Hi Materials Project team,

I am currently experiencing a reproducible issue with the Materials Project web interface.

The homepage loads normally. However, when I click Materials, Apps, Materials Explorer, or directly navigate to a material URL such as:

https://next-gen.materialsproject.org/materials/mp-149

the browser URL changes correctly, but the displayed page remains stuck on the Materials Project homepage.

I have already tested:

  • Multiple computers

  • Multiple browsers

  • Private/incognito mode

  • Different networks and IP addresses

  • Mobile hotspot

  • Logged-in and logged-out states

  • Cleared browser cache/site data

The behavior remains identical.

The browser Console does not show red JavaScript errors. It only shows some yellow browser tracking-prevention warnings.

Importantly, the Materials Project API is accessible from the same machine.
https://api.materialsproject.org/heartbeat returns:

{"status":"OK","version":"0.87.3.dev11+ga5415ca70","pymatgen":"2026.8.30","db_version":"2026.04.13","suffix":"blue"}

Therefore, the API/backend appears reachable, while navigation in the Next-Gen website frontend does not render the target page.

Could you please check whether there is an issue with the current frontend deployment, routing, CDN, or recent identifier-system website update?

Thank you.

Hello,
We are currently investigating and hoping to get a fix in place ASAP.

Things should be back to normal now! Thanks for your patience.

I can confirm that everything is back to normal here. Thank you for your efforts.
