About Let's Encrypt Status Monitoring

IsDown has maintained continuous monitoring of Let's Encrypt, a Security Operations solution, since March 2022. Our database contains 53 documented incidents from the past 4 years, giving us deep insight into Let's Encrypt's reliability patterns and typical resolution times. We parse Let's Encrypt's official status page across all 9 components, interpreting statuses like operational and incident to deliver precise uptime metrics and targeted notifications.

When Let's Encrypt experiences issues, you need accurate information fast. IsDown combines official status page data with user-reported issues, giving you early detection when vendors are slow to acknowledge problems, plus verified incident details once they do. You get affected components, severity levels, and real-time resolution updates from both sources.

Engineering and operations teams rely on IsDown to monitor Let's Encrypt and receive verified outage alerts. Get instant notifications through Slack, Teams, PagerDuty, or 20+ other integrations.

How IsDown monitors Let's Encrypt?

IsDown monitors Let's Encrypt health in almost real-time

Every few minutes we check the status page of Let's Encrypt (and 5,420+ other services) for issues. We collect the status and outage information across all 9 Let's Encrypt components. We also monitor user reports alongside official sources. Since vendors often take time to report incidents, monitoring user reports helps us alert you early.

The moment an issue is detected in Let's Encrypt, IsDown sends an alert and updates your status page

Not only will you get notified, but IsDown offers notification filters so you can choose which issues you want to be alerted about. This way you avoid getting all incidents from Let's Encrypt and other services, focusing only on those affecting your business.

One status page to monitor all your external dependencies

What you get when monitoring Let's Encrypt with IsDown

Track Let's Encrypt incidents and downtimes by severity

IsDown checks Let's Encrypt official status page for major/minor outages or downtimes. A major outage is when Let's Encrypt experiences a critical issue that severely affects one or more services/regions. A minor incident is when Let's Encrypt experiences a small issue affecting a small percentage of its customer's applications. An example is the performance degradation of an application. The moment we detect a Let's Encrypt outage, we send you an alert and update your dashboard and status page.

Get alerted as soon as users report problems with Let's Encrypt

Let's Encrypt and other vendors don't always report outages on time. IsDown collects user reports to provide early detection of outages. This way, even without an official status update, you can stay ahead of possible problems.

All the details of Let's Encrypt outages and downtimes

IsDown collects all information from the outages published in Let's Encrypt status page to provide the context of the outage. If available, we gather the title, description, time of the outage, status, and outage updates. Another important piece of information is the affected services/regions which we use to filter the notifications that impact your business.

Only get alerted on the Let's Encrypt outages that impact your business

IsDown monitors Let's Encrypt and all their 9 components that can be affected by an outage. IsDown allows you to filter the notifications and status page alerts based on the components you care about.
