Hi folks,
I'm afraid that there is an ongoing issue with some of the EDINA WAYFless URLs
that causes a delay in the page loading. So far as we are aware this isn't
related to IPv6 or IdPs being upgraded to Shibboleth 2.x. In the short term you
may be able to work round it by devising IdP-first WAYFless URLs. In the longer
term, EDINA will be introducing a new service interface later in the year, and
there may be new WAYFless URLs, so please check the EDINA website regularly for
updates.
