Configuring a Custom Subdomain

Return

Navigate to Status Pages > All Status Pages and locate the page in the list, using searching and filtering if necessary. Click the name of the Status Page to enter the Manage view. Alternatively, click More Actions > Manage Page.

In the Privacy tab under the Domain section, locate the CNAME field. Enter the desired custom domain that will point to your Status Page (for example, a subdomain such as status.mysite.com or customerstatuspage.com):

In your DNS configuration, create a CNAME record for the subdomain entered in the CNAME field. Set the CNAME Label/Host to the custom domain or subdomain, and point the CNAME Destination/Target to the following address: 

cname.uptime.com

If the CNAME does not appear to be resolving properly to the Status Page, please allow some time as CNAME record changes can take up to 72 hours to propagate. If it still does not appear to be resolving, please send an email to support@uptime.com and we will assist in verifying that the record is setup correctly.

 

Configuring CAA (Certification Authority Authorization) Records for Status Pages

Return

CAA records control which Certificate Authorities (CAs) are authorized to issue SSL certificates for your domain. If you have an existing CAA record or are planning to create one, it must include Let's Encrypt to allow for the automatic issuance of SSL certificates for your domain.

If You Don’t Have a CAA Record

Return

If you're setting up a CAA record for the first time, you’ll want to allow Let's Encrypt to issue certificates for your domain, in addition to any other CAs you trust.

If You Already Have a CAA Record

Return

If a CAA record exists for your domain, you’ll need to ensure that it includes permission for Let's Encrypt to issue certificates. Here's how:

• Access Your DNS Settings: Log in to your domain registrar or DNS provider's dashboard, and navigate to the DNS settings for your domain.
• Modify or Add a CAA Record: If a CAA record exists, check if it includes Let's Encrypt. If not, you'll need to add another CAA record specifically for Let's Encrypt.
• To add or modify a CAA record, use the following values:

Type: CAA
Flag: 0
Tag: issue
Value: "letsencrypt.org"

• Save Your Changes: Apply and save your changes. DNS changes may take some time to propagate, typically up to 48 hours. 

Verifying Your CAA Record

Return

After updating your DNS settings, verify your CAA record using an online DNS lookup tool that supports CAA queries. This step ensures that Let's Encrypt is authorized to issue certificates for your domain.

FAQ

Return

What if I use multiple CAs?

You can have multiple CAA records pointing to different CAs if you use services from various certificate authorities. 

Can I still use Uptime.com without a CAA record?

Yes, a CAA record is not required to use Uptime.com's services. This guide is for customers who choose to use or have a CAA record for enhanced security. 

What should I do if my DNS provider does not support CAA records?

If your provider does not support CAA records, it's not a blocker for using Let's Encrypt with Uptime.com. However, for added security, consider using a DNS provider that does support CAA records.
