Other than discord, no announcements have really been made on the topic.
I realise developers are very busy right now with the issue, as they can be very difficult to fix - When available, will an official announement be made explaining everything and expected times the server will be back online?
For anyone who doesnt know what DDoS is, let me help; DDoS, is where a number of IoT Devices, usually Infected Computers, Servers and so on are all given ocmmands to repeatedly ping an IP address in the hopes of overloading it. Precautions can be made against this, however I'ts very difficult to defend against. Aswell as this, DDoS required almost zero hacking experience. This is where the term 'script-kiddie' comes from. The people behind it are most like 'script-kiddies' who have found a Botnet online and are fingerblasting the server. TL;DR, Some kid has bought access to a Botnet and is using thousands of devices on the network to overflow the server in hopes of it crashing.
Will we be getting any updates soon?
