This is not a DDOS, Tell the truth SE.

[RedDeathXR]

DDoS attacks rarely attack the game servers directly and instead hit a particular internet node. This causes only certain people that connect via that node to be affected by the DDoS attack.

Unfortunately, in many of these cases Square Enix has little control over these issues as it's outside of their network, yet people will blame them anyways because they don't understand the specifics as to why they got DC'd and cannot reconnect.

"Square Enix has little control."

Yes. The only game where this regularly happens for multiple years long now.
