The obvious answer as to why Xbox Live has been up and down (but mostly down) over the last couple of weeks is, of course, that the service has undergone a massive distributed denial of service attack. (Feel free to blame the illusory Sony / Nintendo fanboys, if you must.) Naturally, we're already starting to see some of those rumors catch hold, in no small part due to the fact that while GM of Xbox Live Marc Whitten did offer a free game for peoples' trouble in his public memo a few hours ago, he didn't speak to the cause of the outages. We did, however, get some conclusive inside information from a trusted source, and confidently relay to curious Live users that the issues were not at all related to a malicious attack. Yeah, we know, it tones down the drama quite a bit (and actually makes the Xbox team look a little worse than if they were attacked), but the speculation that the service was out due to a two week long internet assault? The stuff of myth.
