What time did it start? I was on from about 9-10 central this morning doing bounties in Destiny before I left and had no problems. I can't even get to the Xbox status page now. Damn script kiddies. I'm not home yet so it isn't really effecting me, buy sucks for all those who just want to try out their new toys.
I had got on about 11:30 or 12 EST and couldn't do anything. The system would log me in, but I couldn't log into Live at all. At that time there was no message on Xbox.com/status so I tried a bunch of stuff thinking that maybe it was on my end. Finally at about 1EST is when MS acknowledged the issue on their end on the site. Since then, I've been periodically checking the site, and most the time it won't load, or if it does it takes upwards of 5 minutes. It isn't a huge problem for me, but it does suck for the people that just got the system and wanted to at least get updates and games installed before heading out for the day.
Although some of the articles I have read said that the attacks started on Christmas Eve. I was on up until about 5AM EST this morning with no issues though, so it is hard to say when it actually happened. It may have started while you were playing as I believe the way that they work is that it won't kick you from the service if you are already signed in.
it's coming back online now. I was finally able to sign in and purchase Child of Light on sale.
I still am having trouble with the site, and they still have that service is limited on X1, 360, and other devices.
NOTE: I just fired up my One while typing this and it is loading up the dashboard as if I was online, but won't auto sign-in. Then when I do get my actual profile signed in, it goes back to showing as though I'm not connected to Live. Personally, it is more irriating than anything due to the fact that MS and Sony both knew that there was a good chance this was going to happen, so you think they would have better prepared for it. I understand it is a DDOS attack and that it isn't exactly the easiest thing to prepare for, but seeing as we are talking about two of the biggest technology companies in the world... You'd think that greater efforts could have been made to prevent this.
I do have a side question though... How do these DDOS attacks play in to those with Windows phones (if at all)? Does anyone have one or any experience as to what happens to the phone when the attacks happen?
