Welcome to the DownBad documentation. Everything you need to set up monitoring, understand your checks, and keep your sites healthy.

Something is broken right now

False Positives (Down But Not Really) The monitor says down, the site loads fine. Find out which one is wrong.

SSL Certificate Expiring Renew, deploy, and verify a certificate before it takes the site down.

Slow Response Times Split the request into DNS, TCP, TLS, and application time, then fix the slow part.

DNS Records Changed Unexpectedly Records that changed without you, and hostnames that stopped resolving.

Domain Registration Expiring Renew before the grace period ends and everything on the name stops at once.

Domain Blacklisted Find why the IP behind your domain was listed, stop it, then request removal.

Email Domain Blacklisted Work out which address is listed, fix the source, and rebuild sending reputation.

Not Receiving Notifications Tell a configuration problem from a delivery problem in about a minute.
