PulseBoard — AI that investigates why your site broke (real 404 breakdown)
Hey SaaS Hive 👋
I've been building PulseBoard — an uptime monitor that doesn't just alert you, but actually explains what went wrong.
Wanted to share a real example from a live site recently. Not a demo — this actually happened.
📉 The Incident:
404 error at 04:10:01 UTC
Uptime dropped to 93% (baseline 95.8%)
🔍 Vigil AI scored 3 commits:
1. Commit df9f721 (04:07:00 UTC) — Score: 96/100
→ File indexolderbcvvvededehdeh.html was deleted
2. Commit 3b24abd (04:11:47 UTC) — Score: 40/100
→ CSS/JS links were commented out
3. Commit 5694025 (04:10:52 UTC) — Score: 35/100
→ New HTML with broken syntax was created
🧠 What Vigil found:
"Deletion of indexolderbcvvvededehdeh.html caused a 404 — likely a broken reference on the root page."
💡 Why this worked:
✅ Commit deployed 3 minutes before the 404
✅ Later commits correctly ruled out
✅ Clear evidence chain: deployment → file deletion → 404
🛠️ Actionable fix:
Check index.html for references to the deleted file.
Alert → evidence → root cause → fix in under a minute.
Would love your feedback:
Does this solve a real problem for you?
How do YOU currently debug outages?
Happy to answer any questions. 🙏

AWS had an incident today and I had to stop my server 🤦🏻♂️. A few minutes later I received a notification from PulseBoard that my server is down 🙂. It works! Congratulations, Haseeb! I think it has also notified me that my server is back online. But I have not checked my emails yet. I am still recovering from the shock I received from today's AWS incident 🤦🏻♂️.
Sergey — this means a lot. Thank you for taking the time to share your experience. I'm sorry you had to deal with the AWS incident, but I'm glad PulseBoard detected the outage and notified you. And yes—it should have sent you a recovery notification as well. It's great to hear the monitoring and alerting worked end-to-end during a real incident. By the way, your incident postmortem has also been generated for your 4h 12m outage. Since GitHub and AWS aren't connected to PulseBoard yet, Vigil AI couldn't determine the exact root cause from the available evidence. If you're ever interested, I'd be happy to help you connect them—those integrations give Vigil much richer context for investigating incidents and correlating them with deployments or infrastructure changes. Thanks again for using PulseBoard in production and for the feedback. I really appreciate it, and I hope the AWS recovery wasn't too painful. 🙏
This evidence chain layout is great, deployment to file deletion to 404 in under a minute is exactly the kind of thing that saves you from guessing at 4am. The AWS story in the comments is a good real world proof point too. Curious how you handle cases where a few commits land close together and the evidence is more ambiguous than this one, does Vigil just lower its confidence, or does it still try to pick a top suspect?
As a visual person I really appreciate when technical things are explained with real examples like this. The commit scoring with the timeline makes it easy to follow even if you're not deep in DevOps.
