When Microsoft 365 Gets Hijacked,
Your Runbooks Are Your Last Line of Defense

May 2026 · 10 min read

The FBI just warned that cyber attackers are actively hijacking Microsoft Outlook, Teams, and 365 logins. For data engineering teams, that's not just an IT problem — it's an incident waiting to happen. Here's why AI-powered runbooks are the difference between chaos and control.

When Layoffs Hit Your Data Team, Knowledge Walks Out the Door

May 2026 · 15 min read

"When our expert got let go, we didn't just lose a colleague — we lost the person who held the answers to our most critical questions. The stress that followed affected everything."

The $600K problem
hiding in plain sight.

December 2025 · 8 min read

Data engineering teams spend an estimated 60% of their time on reactive operational toil. At an average fully-loaded cost of $200K per data engineer, a five-person team burns roughly $600K annually on work that a well-structured runbook could reduce by half.

The blast radius question
nobody asks first.

September 2025 · 5 min read

Before you start debugging, you need to know what's downstream. Most engineers jump straight to root cause. That's why they often fix the pipeline but miss the backfill that three dashboards needed.

Schema drift kills more pipelines
than any other incident.

November 2025 · 6 min read

Your upstream team renamed a column. Your pipeline doesn't know yet. This is the story of how schema drift accounts for 15% of all data incidents and how to build a runbook that handles it gracefully when it happens.

Incident response

Why severity classification
is the most skipped step.

November 2025 · 5 min read

P0 through P3 aren't just labels. They're a contract with your stakeholders about response time and escalation. Most teams skip classification entirely and go straight to debugging. That's how P1s turn into P0s.

Onboarding a new engineer
shouldn't require a senior.

October 2025 · 4 min read

If your new hire can't resolve a P0 incident using only the documentation in their first month, that's not a problem with the hire. It's a problem with the documentation. Here's how to fix it.

Runbooks rot.
Here's how to keep them alive.

September 2025 · 6 min read

A runbook that was accurate eight months ago but references a deprecated tool and an engineer who left is worse than no runbook. It gives false confidence. Three practices that keep runbooks from going stale.
