Because of vulnerabilities in the SSLv3 security protocol, C&CZ has switched off support for this protocol on all C&CZ managed web servers. A secure connection will thus use the successor protocol TLS. Browsers like Chrome, Internet Explorer and Firefox will each sooner or later stop supporting SSLv3. There is information on how to manually adjust settings to eliminate the vulnerabilities immediately. This can however lead to problems with websites that need SSLv3, such as BASS. P.S.: as of mid-December BASS can be used without SSLv3.
