Hey there,
ALEXF2230! I'm extremely sorry to hear that you were DDoS'd upon returning to Rainbow Six Siege. Your annoyance and disappointment are completely understandable! While Support is not able to restore lost ranked points or adjust rank, we can still get instances like this reported. I will certainly share this situation and your comments with the team. If you experience this again in the future, please try to get videos and/or screenshots of your connection being interrupted and send it to our team at
support.ubi.com. They would be glad to forward your reports along for you. Your help would be greatly appreciated!
