So apparently someone figured out how to DDoS the actual Ark server(s) and thereby increasing the log files to 80gb+
The result is all save files from this weekend are corrupt and cant be used (I was away and unable to react before now)
Nevertheless after much troubleshooting we came to the conclusion that a 3 days rollback would suck to much and therefor the server will be wiped. (even then some player and tribe files would still be corrupted and possible crash the server)
Sorry to everyone for the trouble caused and hope you understand this is the best option.
We need to ensure this wont happen again and do minor tweaks and expect tp be up around 17:00 cest
In another word:
WIPES and back @ 17:00 CEST
