Has someone actually gotten a response from HashOcean lately or are they just guessing what is going on?

Has anyone tried to call their phone number?  I understand it is a San Francisco number USA.  Can someone close try it and see what they get?  That would probably confirm whether they are out of business or not.  (1-650-603-5816)  I am not invested enough, thank goodness, to make it worth my while to try to call.  Also I am in the Philippines.
