Cloudflare sends DDoS reports via email from
[email protected] to users with the Super Administrator role on accounts with prefixes advertised by Cloudflare.
Reports contain the following information:
- Total number of DDoS attacks
- Largest DDoS attack in packets per second (pps) and bits per second (bps)
- Changes in DDoS attacks compared to the previous report
- Top attack vectors
- Top targeted IP addresses
- Top targeted destination ports
- Total potential downtime prevented (a sum of the duration of all attacks in that week)
- Total bytes mitigated (a sum of all the mitigated attack traffic)
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 10th, 2020 summarizes activity from Monday the 2nd to Sunday the 8th.
