3AMSRE
Helping SREs eliminate 3AM incidents - and handle the ones that actually matter.
Real-world runbooks, incidents, and systems that actually work.

I'll send new runbooks and incident notes when they're ready.
What good looks like at 3AM
This is how a controlled incident feels.
Controlled Incident
03:17 UTC
Alert points to real user impact
Signal is correlated, not just noisy
Right person is already on it
Ownership is clear
Clear next steps exist
Known mitigation path
The right person is on it.
They know where to look.
The fix is already moving.
Most teams don't operate like this at 3AM.
Not because they're bad engineers.
Because alerts are noisy, ownership is unclear, and runbooks don't exist where people actually need them.
That's what 3AMSRE is built to fix.
Philosophy
Most 3AM incidents are not random.
They come from noisy alerts, unclear ownership, weak runbooks, hidden coupling, and systems that fail under pressure.
Root cause patterns, not bad luck.
What you’ll get
Serious SRE fieldwork.
Practical writing for engineers who carry production systems, not abstract reliability theater.
Incident runbooks
Clear actions for the first 15 minutes.
Alert noise breakdowns
Separate symptoms from real user impact.
Reliability patterns
Practical patterns for safer systems.
On-call survival notes
How to think clearly under pressure.
Postmortem thinking
Turn incidents into system improvements.
Real-world SRE notes
Field-tested lessons, not theory.
