Knowing which sites can fail over, before it matters.
Our hosting clients need their sites to survive a server failure, so we built a panel that checks each site every minute, through the CDN and on each server, and only calls it ready when both serve the same page.

- What they wanted
A standby server only helps if it’s in sync, and nobody could say which sites were. Our hosting clients need their sites to stay up if a server goes down.
- How we approached it
We made “ready” strict: both servers serve the same page. Anything else goes on the to-do list with the next step written in.
- What we delivered
- A live matrix of sites by server
- Sync checks with the next step written in
- A list of server issues
- No dependencies, so it runs anywhere
