Yeah im having the same problem, i can't play and im usually getting error codes or contacting destiny servers. I check my internet and i can play other games fine, but destiny is the only one i can't play at all. I look up the error codes and there's no help at all, the only thing there is "we are investigating this issue" don't worry you aren't the only one, allot of people are experiencing this and if bungie magically responds they will tell you it's your internet or something.
