Find the SEV-1 before it finds prod.

Weekly email-based drills that uncover your team's infra blind spots. GPT pushes you to failure, then coaches.

This product helps mid-market engineering teams sharpen their production instincts. It's a weekly fire drill, over email.

GPT drops you into a SEV-1, and makes you explain your thoughts until you hit a wall. No UI. It just shows up in your inbox and applies pressure.

Test first, find the blind spot that will eventually crash production, then coach.

Re: The GC job that looked safe Mon, Jul 7 • 9:17am

replicate.info

A job starts garbage collecting a soft-deleted Organization with 400k dependent records, all in one transaction. pg_stat_slru shows 87% usage on MultiXactOffset. What's your first move here?

Alex Shaw

I'm not sure what that is, but I think we had something similar when deleting old customer records. The site got slow, so we killed the job and just looped through deletes in the console.

That works until high-fanout DELETEs grab locks for FK checks, and SLRU exhaustion kills reads/writes across the site. Let's try again.

GPT drops you into a SEV-1 with some clues, and makes you explain your thoughts until you hit a wall. No UI. It just shows up in your inbox and applies pressure. Surfacing fatal blind spots is a good thing, just not inside a prod console at 2:00am.

No logins. No credit cards.

Next Steps

You get the first SEV immediately. No demos or setup. 100% async.

It emails a new infra puzzle every Monday, which you'll scramble to fix in private threads. The more you think out loud, the better GPT can uncover blind spots. Here's what the first email might look like.
