Xbox Live Hacked?

Ok, so about thrity minutes ago I was sitting here in my room playing Halo 2 on Xbox Live. I was running around on Lockout with my sniper rifle gracefully when it happened. Just as I go to snipe somebody, I get the 'ol 'Xbox Live Not Found; Start Troubleshooter?' message.

After spending 10 minutes reconfiguring my router, I was finally able to sign back in and join my buddy's party.

Turns out, everyone on Xbox Live (or possibly just everyone on Halo) lost their connection. So we just say 'leave it to Microsoft' and go on brutally killing each other and chatting. Then, while in the middle of a conversation, everyone gets booted off again. This time, I couldn't get back online. I signed in long enough to see that my clan had disappeared and that everyone on my friends list was offline. After screwing with my xbox and router for about 5 minutes, I finally said 'screw it' and now I'm writing this.

So what happened? Was Bungie hacked? Was Xbox Live hacked? Was it just a bug in the server? How can my deleted clan be explained? If this was a server error, Microsoft is probably going to get a LOT of flaming from websites and blogs (including this one). Guess we'll know tomorrow... I'll keep you updated with any information I get on the subject.
