Supported Features

We support the following features in our integration with the Let's Encrypt status page:

  • Down Notifications

    If Let's Encrypt is having system outages or experiencing other critical issues, red down notifications appear on the status page. In most cases, it means that core functions are not working properly, or there is some other serious customer-impacting event underway.

  • Warn Notifications

    Warn notifications are used when Let's Encrypt is undergoing a non-critical issue like minor service issues, performance degradation, non-core bugs, capacity issues, or problems affecting a small number of users.

  • Differentiates Maintenance Notices

    Let's Encrypt posts separate notifications for planned maintenance work. StatusGator will notify subscribers when Let's Encrypt enters a pre-planned maintenance window, keeping you up to date.

  • Proactive Maintenance Monitoring
  • Status Overview

    When Let's Encrypt posts issues on their status page, we collect the main headline message and include that brief information or overview in notifications to StatusGator subscribers.

  • Status Details

    When Let's Encrypt has outages or other service-impacting events on their status page, we pull down the detailed informational updates and include them in notifications. These messages often include the current details about how the problem is being mitigated, or when the next update will occur.

  • Component Status Filtering

    Because Let's Encrypt has several components, each with their individual statuses, StatusGator can differentiate the status of each component in our notifications to you. This means, you can filter your status page notifications based on the services, regions, or components you utilize. This is a very useful feature for complex services with many components or services spread out across many regions.

Let's Encrypt status page says the service is up, but I'm having issues. What's wrong?

There may be several reasons for that:

  • An outage that hasn't been communicated yet via the Let's Encrypt status page.
  • Some local issues with a small group of accounts on the service side.
  • Technical issues on your side, or problems with your software or ISP.
  • A misconfiguration on your side.

We recommend contacting Let's Encrypt customer support while checking everything on your side. You can also try Tweeting at them via @letsencrypt on Twitter. Or visit their official status page or website:
