About Let's Encrypt Status and Outage Monitoring
IsDown has monitored Let's Encrypt continuously since March 2022, tracking this Security Operations for 4 years. Over that time, we've documented 53 outages and incidents, averaging 1.2 per month.
We monitor Let's Encrypt's official status page across 9 components. IsDown interprets Let's Encrypt statuses (operational and incident) to deliver precise health metrics and filter alerts by the components you actually use.
When Let's Encrypt is down, IsDown combines official status data with user reports for early detection. Vendors often delay acknowledging problems, so user reports help us alert you before the official announcement.
Engineering and operations teams rely on IsDown to track Let's Encrypt status and receive verified outage alerts through Slack, Teams, PagerDuty, or 20+ other integrations.
How IsDown Monitors Let's Encrypt
IsDown checks Let's Encrypt's status page every few minutes, across all 9 components. We combine official status data with user reports to detect when Let's Encrypt is down, often before the vendor announces it.
When Let's Encrypt status changes, IsDown sends alerts to your preferred channels. Filter by severity to skip noise and focus on outages that affect your business.
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
