From http://blog.libertyreserve.com/ Temporary Outage While doing a regular system check, our technicians recognized a defective load balancer and had to temporarily suspend the servers to replace it. We are working very hard to fix this issue and get the system back online. The number of our clients and merchants is growing rapidly. Our hardware grows even at a faster rate. Although this is a definite sign of success, there might be temporary outages, which are beyond our control. We will do our best to provide you with the service you expect. Thank you for your support.
They are down due to DDOs attack very often. Some say its the russian payment processors doing that to gain market. They always seem to come back. They are online now.. DL
