In a perfect world, we would be able to support the AS network further. But it is not feasible from a financial standpoint.
It's like asking a store clerk for a $20 game when your wallet is empty and you're already in indebted to him for $30. No matter how much you may beg for the game with claims of how much you loved its demo, the reality is that the game costs $20, and you just can't pay that. The appropriate response is not to claim that the game costs too much or that the store clerk just doesn't care about you or his/her customers (or worse, steal the game); the appropriate response would be to either accept your circumstances and admit you can't buy the game, or work to change your circumstances so that you can afford the game at a later date.
I'm going to admit that I don't know as much about the networking and technical side of this argument as well as the Dave, the Developers, and Chad do, but I trust their knowledge and experience. The AS situation is one that has been thought over for several months, and know that they would have explored the possibility of every option before concluding on this one.
As much as I value the players' opinions on this matter, I would side with the professionals on matters as technically complex as this one. It's not a matter of renting servers from other hosting services (which wouldn't be worthwhile for gameplay purposes, and would create problems as we wouldn't have full server box access to configure for our plug-in), nor is it a matter of buying a micro-sized server (which isn't really possible and definitely not financially efficient). There are a lot of complexities and considerations that people do not realize exist until they've done it, and that goes for a majority of people posting in this thread. But when it comes to the Developers, I know they understand the full picture: they've been doing this time and time again for the last few years.
That's not to say that the loss of the AS community wouldn't be tragic: the fact that this thread even exists shows us that the AS region had a handful of players who were dedicated to it and are thus sad to see it go. It was a region that resembled a small community of a max of 30-50 people, a mere fraction compared to the Australia region's average numbers. However, with all small communities, they were a tight-knit bunch of friends who were quite loyal to the servers that they loved.
I think
savva60 's post really summarizes the perspective of the AS players:
....
MCSG is a haven for AS players. It's a competitive, close-knit community. It is beloved to us, sacred to us. And you are taking it away for 'economical reasons'.....
Please continue this run of kindness, please bring back AS.
But the reality of the matter is that having dedicated AS servers is not feasible, and thus a shutdown as inevitable. No matter how many friends you may have met, no matter how many games you may have played, no matter how much you love the servers, there's no getting around the fact that such servers cost money and time which must be paid for. And there were not enough Premium Rank upgrades from the AS region to justify the costs on a month-to-month basis. The other regions have a population large enough to have enough regular Premium Ranked members to be sustainable for all, but the AS region was too small to maintain that same dynamic. Unless a section of the AS playerbase suddenly devotes itself to the price of monthly upgrades (something I doubt players would be willing to do), bringing back AS just isn't practical.
We were bleeding to keep AS open for as long as we did, but it came at the cost of attending to the other, more populated regions; the needs of the many come before the needs of the few. It might not be nice nor what anyone wants, but it's the grim reality of the current situation which we must respond to.
