We are being attacked by a new DDoS attack today which causes some slight performance issues on our servers.
The situation is being worked on and hopefully the attack should be mitigated completely soon.
Updates will follow.
Update 21:30 (Server Time)
We've made some changes on our end (our provider have on their side as well) which should make future DDoS attacks have somewhat of a lesser impact on our servers. We will continue to monitor the situation.
