Do people like you just post this without even attempting to investigate anything on your own? 90% of the time it isn't the fault of the servers. Destiny is a peer-to-peer game, so either your connection or the hosts connection is at fault. They have pages on their site AND mobile site to check error codes just for this occasion. Here's fixes: make sure your firewall isn't blocking you, make sure your router is actually a newer one because older ones rarely work properly with Destiny, switch from wifi to wired if you haven't already, cut down on the number of devices pulling from your bandwidth at once, make sure your ISP isn't having issues in your area, and make sure all of your hardware doesn't have an issue itself. (Hardware, in this case, being any ports in routers/consoles and all cables.)

Destiny, the only game that has more shitty servers than original CoD/Battlefield games
