There's a known problem with StartCom's OCSP responder returning "Unknown" for newly-issued certs (see bug 1006479), but that shouldn't apply to a cert apparently issued four months ago. For a newly issued cert "unknown" probably means the cert issuing server hasn't updated the OCSP responder yet. For a months old cert it's an alarming response -- if you (the CA's OCSP responder) never heard of this cert is it fraudulent, stolen by a hacker? [Note, I'm not questioning your cert, I'm explaining the reasons some browsers consider "unknown" a bad response.] If the StartCom server is having temporary trouble it would be better if they returned "tryLater" responses. If they've truly lost track of having issued your cert that's alarming.
Due to a technical issue the OCSP responders failed to update - they are syncing again and this issue should resolve itself within the next few hours for your if it haven't already. Make sure to restart your Firefox before trying again (since the unknown response is cached also).
...for your site...
Indeed, it looks like the OCSP responder issues have been resolved.
