We are under attack from nine days. Our servers receive a lot of fake traffic. At this time our free servers NS3 and NS4 are down, because they can't operate with this amount of bandwith. Our free servers NS1 and NS2 continue working.
Web redirects was moved to another servers and at this time they works fine.
If DDoS attack continue in future we will start other servers on NS3 and NS4 to continue serving good free service.
