Hi! I'm the developer of GCC Explorer and ... sorry for the slow service! This is the second time I've made it on HN - thanks for all your support. GCC Explorer runs on an Amazon EC2 instance and my "secondary" instance that I spin up from time to time is woefully out of date...
Better late than never...I've increased the power and number of instances running GCC Explorer, so hopefully it's a lot more usable under load now. Although my HN 5-minute fame seems to be over now :)
