Learn how Cloudflare DDoS reports summarize attack intelligence. Reports are available to Magic Transit and Spectrum BYOIP customers.
Cloudflare DDoS reports provide convenient weekly summaries of L3/4 (network/transport layer) DDoS alerts to Magic Transit and Spectrum BYOIP customers. Each report is a snapshot of the DDoS attacks that Cloudflare detected and mitigated in the previous week. Reports highlight insights, trends, and recommended actions.

When Cloudflare does not detect any L3/4 DDoS attacks in the prior week, Cloudflare sends a confirmation report:
Cloudflare issues DDoS reports via email each Tuesday. Reports summarize the attacks that occurred from Monday of the previous week to Sunday of the current week. For example, a report issued Tuesday, November 10, 2020 summarizes activity from Monday the 2nd to Sunday the 8th.
Cloudflare sends DDoS reports to users who have the Super Administrator role on accounts with prefixes advertised by Cloudflare.
