Where does Uptimus get the official Lets Encrypt status?

Uptimus reads the official Lets Encrypt status source and normalizes its incidents, maintenance windows and component states. The links below let you verify the provider information directly. Lets Encrypt Status Page: https://letsencrypt.status.io Lets Encrypt Home Page: https://letsencrypt.org

Lets Encrypt says it is up, but I am having issues. What could be wrong?

The official page may not yet reflect a new incident, the problem may affect only a small group of accounts or one region, or it may be local to your device, network, software or ISP. Check the affected components and community reports above, test another connection or device, and contact Lets Encrypt support if the problem continues.

How can I check whether Lets Encrypt is having issues?

Compare the normalized status and recent incidents on this page with the official provider source. Uptimus keeps official component changes, maintenance, community reports and recent incident details together so you can distinguish a broad outage from a local problem.

How to get notified about Lets Encrypt outages?

Add Lets Encrypt to your Uptimus workspace, then choose the event types and delivery channels you want to use. Depending on your plan and configuration, alerts can be sent by email, push, webhook or configured integrations for major outages, smaller issues, maintenance and recovery. If Lets Encrypt exposes components, you can monitor all of them or restrict official alerts to the products your team uses.

Component status filtering

Choose all components or only the Lets Encrypt products you use. Official alerts then respect that component selection. Uptimus currently tracks 12 Lets Encrypt components: acme-v02.api.letsencrypt.org (Production) - High Assurance Datacenter 1, acme-v02.api.letsencrypt.org (Production) - High Assurance Datacenter 2, acme-staging-v02.api.letsencrypt.org (Staging) - High Assurance Datacenter 1, portal.letsencrypt.org (Production) - High Assurance Datacenter 1. Filtering changes which official alerts are delivered; it does not remove the provider's events from the public history.
