Q4 2025 DDoS report: turn extreme records into drill questions
Use the report as threat context and turn it into concrete operational readiness checks.

Keep the reported record in context
Cloudflare’s February 5, 2026 report on Q4 2025 described a 31.4 Tbps attack. That record does not establish the capacity of every protected-IP plan or describe WAFPRO’s delivered resources.
Make drills action-oriented
Ask who confirms an incident, contacts upstream support and approves degradation; which transactions must remain consistent; and how recovery is checked. Turn answers into steps the on-call team can execute.
Validate alternative access in advance
Test backup DNS, certificates, origin permissions and client switching before an incident. Fixed-IP clients and persistent sessions need separate address-change and reconnect validation; a DNS update does not immediately move every user.
Feed findings back into design
Record uncovered ports, unanswered alerts and dependencies with only one access path. Use those findings to choose mitigation upgrades, application capacity or architecture changes instead of buying solely against headline figures.
