As reported earlier on twitter, there are access issues to Springer content – both e-books and e-journals. The publishers have now restored Shibboleth authentication which means all users can now access content again.
To access the Springer content via Shibboleth authentication, click the sign up/log in link located at top right corner of any Springer webpage and follow the on-screen instructions for Shibboleth.
Springer continue to work on IP address/EZProxy authentication. UPDATE – all technical problems fully resolved 29/9/15
