Unfortunately many of our more recent developments in the DDoS situation are things that we cannot share with the community for security reasons. We are still working daily finding new ways to improve things in the short term while we wait for the permanent DDoS filtering is being set up. Please do keep in mind there may be a "fine tuning period" once this new filtering is in place.
We are aware that some of our temporary protections have been blocking some community members from accessing the game. We built a temporary white list feature to work around this but are running into issues with the service provider's API this feature needs to hook into (them blocking our prod box's IP automatically). If this is resolved before we get our full DDoS protection we will make an announcement with instructions on how to white list IPs for those struggling to connect.
