Crashes and timeouts
Trace logs, exceptions and infrastructure signals to identify failing requests, resource pressure and recurring errors. Establish the incident scope and customer impact.
Services for existing applications
Ruby on Rails rescue for a troubled application
Recurring crashes, stalled jobs and broken integrations can make every release feel risky. We diagnose the immediate failure, restore dependable processing and leave a recovery plan your team can use.
Start with the failure affecting your business
Stalled jobs and broken integrations
Inspect queue state, retries, external API failures and webhook processing. Check duplicate-processing and data consistency risks before retrying or replaying work.
Unreliable deployments
Review release steps, configuration, migrations and rollback options. Identify the changes that make production fail and the access needed to recover safely.
Diagnosis, stabilization and recovery
Diagnose and agree a recovery plan
Document the likely root cause, affected workflows and immediate options. Agree the safest recovery steps, responsibilities and communication cadence.
Stabilize production
Implement the agreed fixes, restore processing and verify critical workflows. Make retries and recovery explicit so a restart does not conceal the underlying problem.
Reduce repeat incidents
Add targeted tests, monitoring and error handling. Separate immediate fixes from the larger upgrade, refactoring or infrastructure backlog.
What recovery leaves behind
We agree access, availability and response arrangements before starting. The initial discussion establishes whether the required incident coverage fits our capacity.
Incident findings and validated fixes
Receive the diagnosis, changes delivered, checks performed and any unresolved risks. Validate recovery with request errors, queue progress or integration consistency as appropriate.
Recovery runbook and next priorities
Document operational checks, escalation contacts, rollback and replay steps, plus a prioritized follow-up backlog. Agree ongoing maintenance separately when the application is stable.
