Hi all!

in order to tighten the security at cat.eduroam.org

we plan to discontinue the support for TLS versions 1.0 and 1.1
at the web site https://cat.eduroam.org.

We witnessed very low [1] usage of TLS version < 1.2. so we expect this
will not be a problem for you.

Maintenance is planned for September 8 (8:00 a.m. CEST).

Please let us know if you have any questions or concerens not later then
Semptember 3.

Kind regards

Miroslav Milinovic
eduroam service manager
