This is a free, hackable uptime/downtime monitor that sends you an email when the site doesn't return a 200. It also stores historical uptime and latency data in your Val Town SQLite, which is used to power a status page.
Pull requests welcome!
The awkward piece is that if your config.json might conflict with mine. No worries! Just send the PR anyways, and I'll be sure to get my config.json back into shape after I merge your PR.
