i believe xbox live and destiny servers are having huge issues. why it affects some like myself with xbox 360 with extreme high speed (150+mbps) service is a unanswered. destiny techs, xbox live techs have been mum on what is happening on their side. they have asked me to reset modem, router, xbox, set up dns, dmz, ip addresses which did not solve anything but give me a degree in networking. now i check this website to see if it affecting others like me, getting sent to the main screen sometimes with no error code other than you have been dissconnected from xbox live.

please post if you find a solution
Or like me and on top of booting every twenty minutes, it will lock the system every hour and I have to unplug it, and plug it back in, and it might work for another hour.
