Disaster Recovery Testing
Your disaster recovery plan is only as good as your last DR drill. We design and run structured disaster recovery tests — simulated failures, timed recovery procedures, gap analysis, and remediation tracking — so your team builds muscle memory for real incidents.

We implement, you ship. Async, documented, done in days.
Test Scenario Design
We design DR test scenarios based on your risk profile: primary database failure, complete AZ outage, DNS provider failure, certificate expiration, ransomware simulation (restore from immutable backup), and accidental data deletion. Each scenario has defined success criteria: maximum acceptable recovery time, data integrity requirements, and service-level objectives that must be met post-recovery.
Controlled Failure Injection
Depending on your risk tolerance, we run tests in isolated staging environments or production. Staging tests use cloned infrastructure with replayed traffic. Production tests use controlled failure injection — terminate a replica, block network to the primary, rotate a credential. We use chaos engineering tools (Litmus, Gremlin, or simple iptables rules) with kill switches to abort if blast radius exceeds expectations.
Timed Recovery Execution
During the drill, your team follows the runbook while we observe and time each step. We measure: time to detect the failure, time to diagnose root cause, time to initiate recovery, time to restore service, and time to verify data integrity. Each measurement is compared against RTO/RPO targets. We note where teams hesitate, where runbooks are unclear, and where automation would save critical minutes.
Gap Analysis and Remediation
Every DR drill produces a gap analysis report: what worked, what failed, what took longer than expected, and what was not tested. Each gap gets a remediation item with priority, owner, and deadline. Common findings include: outdated runbooks, missing automation, untested restore procedures, and credential access issues. We track remediation items across drills to show improvement over time.
