01 problem
A website database corrupted during a hosting migration. Separately, a deployment exhausted server resources and took production offline. A third event looked like a bulk data exfiltration attempt.
02 solution
For the database, I analyzed monitoring data and server logs, restored from an earlier backup, and completed the migration. For the outage, I traced the cause through monitoring, application logs, container health, and utilization, then corrected the deployment configuration. For the exfiltration, I used Workspace access logs and source IP data to identify the account, revoked its access, and assessed what it had touched.
03 impact
Each incident ended with a durable change, not just a fix: a migration SOP and developer training on backup and recovery, enhanced monitoring with a documented recovery procedure, and stronger download alerts with a briefing to executive leadership.
One incident, step by step
The deployment that exhausted server resources, at Twin Designs and Tech:
- [ALERT]Production unavailable after a deployment exhausted server resources
- [TRIAGE]Monitoring data, application logs, container health, system utilization
- [FIX]Corrected the deployment configuration and restored availability
- [HARDEN]Enhanced monitoring and a documented recovery procedure
Why the write-up matters
The restore is the part people remember. The procedure is the part that keeps it from happening twice. Every one of these incidents ended with a document a developer or an executive could act on without me in the room.
