   Interesting observation re: the distributed denial-of-service (DDoS) attack on mastodon[.]social: it almost seems like the technique involves ActivityPub amplification. Notice how traffic from mastodon[.]social ➡️ fedified[.]com tracks with the attack*

   The increase in traffic originating from mastodon[.]social that coincides with the beginning of the attack, which lasts about 4 hours before finally subsiding (1/3)
