DebConf Organizers blog
Thanks to the work of the Alioth admins and the DSA team, single sign-on services are back online. Everyone will again be able to register for DebConf14 according to the steps described on this page.
We apologize for the inconvenience. Administrators are working to resolve the issue as quickly as possible; we will update this blog once the problem has been resolved.
In the meantime, Debian developers can continue to register using their debian.org SSO credentials.
