Hi, greetings on behalf of the Bilbao Crystallographic Server (couldn’t find a direct contact method, thus I’m writing publicly, as recommended)!
Recently, we have relocated our MAGNDATA database (https://www.cryst.ehu.es/magndata/) from its subserver (which was located at http://webbdcrista1.ehu.es/magndata/) to our main server. In order to ensure legacy-related old links access, we have placed an URL forwarder there, so for example, a query for:
h**p://webbdcrista1.ehu.es/magndata/index.php?index=0.3
automatically redirects the user’s browser to:
h**ps://www.cryst.ehu.es/magndata/index.php?index=0.3
(distorted keyword ‘http’ to ‘h**p’ in order to prevent auto-rendering the link)
But the maintenance of the old subserver won’t be forever and in the future we are planning to retire it…
Materials Project currently presents the external links to the old server (check for instance: https://next-gen.materialsproject.org/materials/mp-1191787?formula=Ca3LiOsO6 ). We would appreciate if you could update the server information in the related entries, if possible…

Thank you very much!
On behalf of the BCS team,
