To echo autographedcat , I'm currently in the US and have not really seen any significant latency - at least, not anything that I didn't experience (arguably, more often) with the old NCSoft servers. In fact, on my newer hardware, it runs so much better that it's basically a new game for me.
Not that it matters (and I mean that!) - but are there any metrics on where, regionally, the donations came from? Perhaps some day that can guide where to place additional servers that target a region, if demand calls for it.
I would really like how you're managing this. I'm hoping this project enables a community of open source MMOs some day - a community like you've been creating has a way of keeping something like this alive for a very, very long time.
If the NPO (once it is an NPO) would accept it, I'd be willing to donate my time; I have experience with multi-continental (banking) and high-traffic (wagering) digital services. You can do a lot with $6k/mo, and that you're doing this WITH $6k/mo tells me you already have a number of experts working on this and probably don't need my help - just know you have it if you ever do. I'll also be donating, if I can ever get in to an open donation window, lol.
Thanks, guys! And keep up the great work!
