Built solo over a weekend for the WeMakeDevs × Zerops challenge. There's a live gateway you can poke at, and a section near the end about what it can't do.

I was testing a GitHub integration with a tunnel open to my laptop. I shut the lid to go get coffee. When I came back, the push event was gone.

Not delayed. Not sitting in a queue somewhere. Gone.

I figured I'd misconfigured something. I hadn't. From GitHub's own docs:

"GitHub does not automatically redeliver failed deliveries."
