There are several clues that indicate an ongoing DDoS attack is happening:

• An IP address makes x requests over y seconds.
• Your server responds with a 503 due to service outages.
• The TTL (time to live) on a ping request times out.
• If you use the same connection for internal software, employees notice slowness issues.

Can you stop DDoS attack?
