I'm in the same boat, this is day 5 of not being able to sign in. I've tried absolutely everything possible on my end and I am sure that the issue is with Bungie and not my connection, network or anything else on my end. I played all last weekend with no issues other than a couple of minor disconnects, came home from work Monday and couldn't sign in and haven't been able to sign in since. I posted my own topic here on the forums detailing everything I've tried and asking Bungie for help and I've received no reply from them, I've even tweeted @BungieHelp on Twitter and received no response from them either. @BungieHelp actually tweeted yesterday that "PlayStation sign issues have been resolved". It would seem that tweet is a little premature because I still can't sign in and there are plenty of people on the forums who are still not able to sign in. I am an understanding person and I can deal with a sign in issue no problem. What I find hard to deal with is the absolute stone wall silence from Bungie on the issue. Even a simple "we know about your issue and we're working on a fix" would keep me and lot of other people happy. We don't even know if Bungie are looking into the problem. They may not be bothered putting resources into a problem that is only affecting a few thousand players out of their several million total players. Come on Bungie, say something! Preferably something other than"we have resolved the issue" because you have not resolved the issue.
