Wow, you know, I haven't even looked at that site in years. (I tried posting on their forums once, and got slapped down hard. Incredibly unfriendly folks on their forum...)
But the Wayback Machine shows that it was up as recently as Jan 15, so if something happened, it can't have been very long ago.
Wasn't too long ago, I checked it and it seem dead like 6 months ago. Dead, just like the mini. jk, the mini is alive and well and in need of attention!
Their domain registration was renewed on/around Jan 15th as well. I wonder if someone else now owns the domain?
[doublepost=1457363797][/doublepost]Looks like it's with the same registrant as it was the past year or two. So my next bet is on DNS screwups.
I tried the wayback machine and I think (going from memory) the last snapshot was from about mid-Jan (could have been the 15th). There was no notice I saw on the front page or in any of the forums about shutting down. I also went to the Twitter site and it hasn't been updated in quite a while (and no notice of a shutdown).
