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)

*the chart is inbound traffic over the last 24 hours filtered by source
