StartSSL down and out?

I tried to login to StartSSL, but the login fails. I get:

An error occurred during a connection to auth.startssl.com. Peer does not recognize and trust the CA that issued your certificate. (Error code: ssl_error_unknown_ca_alert)

I tried different browsers on different computers and different networks. I mailed them - no reaction yet. I tried to create an account on their forum, but it fails on the captcha repeatedly. I tried to login with OpenID, but no success. I created an account with their bugzilla site, and this works, but I cannot create tickets...

Yesterday I tried the first time, today no change. Does this mean they are out of business?
