Hacker News Front Page: what 26 hours of traffic got us

October 23, 20251 min read

I wrote a blog 3 days ago sharing my experience building RAG in production. The post went viral on Hacker News and remained on the front page for 26 hours.

I want to share what it was like on the receiving end, and how we accidentally went viral.

The Story

On Monday, I spent a couple of hours writing up our experience building RAG in production for r/RAG. I hit publish and... nothing. No upvotes. Then I realized Reddit was down.

I was quite bummed. I took the Reddit content, put it in a blog post, and submitted it to Hacker News with zero expectations.

I wrapped up a customer demo call, habitually opened HN. There it was! #6, and shortly after #2 on the front page.

Thanks to AWS for the outage, and thank you to everyone who supported us on HN.
