How can a streamer respond if they are actively under a DDoS attack?

If a streamer is under attack, they should first verify the attack is real by examining server logs and network traffic. Next, they should contact their DDoS protection provider if they have one. If not, they can try temporarily changing their stream's IP address (if possible), and contacting their ISP for assistance. Documenting the attack (screenshots, logs) is crucial for future reporting.
