Your developer is asleep. Production isn’t.
Senior engineering for production incidents, broken deploys and urgent bugs. You reach the engineer who does the work, not a ticket queue.

I’ve accepted this as a P1 incident. I’m starting triage now at the Emergency Rescue rate. Please keep one decision-maker available and send access through the agreed secure channel.
Emergency Rescue · €300/h · 2 h minimum- read-only DB + logs access granted

How a call runs, from report to handoff
Example timings from the call above. Yours depend on the system.
- T+0
Tell me what broke
Impact, when it started, what changed last, the stack, and any safe error or log context.
- T+11
I confirm fit and urgency
If I cannot responsibly help, I say so before you lose more time.
- T+19
We set up safe access
Temporary credentials, least privilege, one decision-maker on your side.
- T+24
Triage first
Find the failure mode, stabilize where possible, explain the next move.
- T+37
Fix or mitigate
The smallest safe change that restores service, then verified.
- T+54
Clean handoff
What happened, what changed and what should be prevented next.
What I tell people up front
When an incident is outside what I can own
“I don’t think I can responsibly own this incident fast enough in the current stack/scope, so I’m not going to burn your time pretending otherwise.”

On guarantees
“I can guarantee the process and response level I sell. I cannot responsibly guarantee the resolution time of an unknown system before triage.”

Impact and one way to reach you is enough to start. Everything else is optional.
