Who hunted Pager?
Pager was hunted by Jonathan Irhodia. A “hunter” on Product Hunt is the community member who submits a product to the platform — uploading the images, the link, and tagging the makers behind it. Hunters typically write the first comment explaining why a product is worth attention, and their followers are notified the moment they post. Around 79% of featured launches on Product Hunt are self-hunted by their makers, but a well-known hunter still acts as a signal of quality to the rest of the community.

Hi, I’m Jonathan, the engineer behind Pager.
I built Pager to give engineers a place to practise investigating incidents before they’re on call. You work through simulated failures, follow the evidence, make a repair, and verify that the service has recovered.

I’m looking for feedback on the investigations and repairs, especially anything that feels different from the systems you work with.
