# Certificate Transparency Uptime Alerts

This is a little service that checks

	https://www.gstatic.com/ct/compliance/endpoint_uptime.csv

and makes it possible to set up alerting for it.

e.g. https://ct-uptime-alerts.fly.dev/geomys.org will return a 503 if any lines
matching "geomys.org" have an uptime column below 99.95.

You can use it with any filter string, and it also takes a parameter like
"?threshold=99.8". You're welcome to use our instance (no guarantees!), or you
can run your own:

There is also a witness monitoring service at https://ct-uptime-alerts.fly.dev/witness/.
