We've put up an updated Preview 1.5.6 with some more bug fixes. Also, we've beefed up the front end hardware a bit so it should be able to handle more people logging in at once.
It will be up all weekend for those who want to try it out.
We're going to do a load test on Monday where we try to get many people to log in and stress the system. We'll be running some load statistics that should provide us with some info about the location of hotspots are in our bandwidth / packet creation, which we expect to be very helpful for optimizing the bottle necks out of our back end servers.
Have a happy Halloween.
