[Koha] Worldcat's xISBN Web service, down?

[Jonathan Druart]

Hello,

We have a test failing because of the xISBN service that is not reachable (
http://xisbn.worldcat.org)
Anybody has info about it?
Should we remove it from Koha? Is it temporary?

Their website does not tell anything about it

Please let me know in order to adjust or remove the code.

Regards,
Jonathan
