SMS, WhatsApp, phone call notifications from Healthchecks.io are currently not being delivered. Our Twilio account is suspended due to a billing issue. The billing issue is fixed, and we are waiting for the account to be reactivated.

Healthchecks.io no longer has team size limits: all users can now invite an unlimited number of users into their projects. https://blog.healthchecks.io/2026/02/unlimited-team-sizes-for-all/

New feature: Healthchecks.io can now classify HTTP pings from clients as start, success, or failure signals by looking for specific keywords or phrases in the HTTP request body.

Signal notification delivery was broken for the last 17 hours. This was caused by our Signal account getting de-registered on April 1. Account now recreated and notifications work again. https://status.healthchecks.io/en/incidents/RKju8zaHfyr265Q7uAEbK7/

Outage: our services are currently down. Looks like there is no UDP connectivity between any of our servers. Investigating.

It's a small thing but... you can now click on slider labels in Healthchecks to set the Period and Grace Time parameters quickly:

We will be upgrading HAProxy on our load balancer servers on Tuesday, January 6, 2026. The planned changes should not affect the vast majority clients, but could in theory cause connection issues for very old legacy clients. If you notice persistent ping request failures starting from January 6, please let us know.

We had a complete outage for about 26 minutes 😬
