I haven't been able to get on at all today. Last night at least it would load sometimes, or give you a message saying it was down - now it's just not there.
From what I got last night, the web host which I believe was named something like GeoVarios is upgradding our servers for free. Apparently in less than a year we doubled in size and were averaging something like 27 million hits a day. So the next couple days are going to be very shaky as they are implementing some sort of RAID type platform so the server will NEVER go down, even on nightly maintenance. The idea is there will now be multiple servers hosting Calguns instead of just one, and as one becomes bogged down, slow, or unavailable the others pick up the pace to cover the lost server until it comes back online. They each update themselves so they always have the same information. In the long run it means a faster more stable Calguns for everyone.
