@TheAdmin Can you share the list so other instances can use it? I'd like to check our logs for ddos events.

@freemo @TheAdmin Yes, please share the IPs, so other mastodon admins can have a look in their logs.

@seb @freemo
The attack source is access from AS Number 2516 (KDDI).
IP addresses change frequently ( but, All are IPv6 addresses).
Maybe, It is an attack that individually targets mastodon.cloud because it contains posts by personal grudge.

A completely different DDoS attack from Russia and Ukraine has become active. These have been confirmed to cause damage to other servers and require attention.
