Affected some Eduroam users

On December 10, the support for the security protocol TLS v1 and v1.1 was discontinued within the Radboud Eduroam wireless network. From that moment on, all wireless clients such as laptops, smartphones, tablets and the like must use TLS version 1.2 or higher.

Unfortunately, the outcome of this change was not as expected. After the change, there were more clients with connection problems than the number of clients using TLSv1. After a period of testing and research, the ISC decided around 12.00 to reverse the change.

Although the underlying reasons are still valid, the termination of TLSv1 support has been suspended for the time being. In consultation with SURF it will be decided in the coming period what caused the problems of the different clients.
