your-slug.tallwatch.com as soon as it exists. A custom domain is a hostname you own, such as status.acme.com, that shows the same page.
How it works
The Tallwatch subdomain needs no DNS on your side. For your own hostname, add two records: a CNAME that sends visitors to Tallwatch, and a TXT record that proves you control the name. After both records pass verification, HTTPS is issued automatically. Use a subdomain (status.acme.com), not the apex (acme.com).
Point a custom domain
When you attach a custom domain, Tallwatch returns the records to create. Forstatus.acme.com:
1
Add both records
Create the CNAME and the TXT in your DNS host. Use the exact TXT value Tallwatch returns for that page.
2
Verify
Trigger verification (app or API). After both records pass, HTTPS is issued automatically.
If checks fail, confirm your DNS UI did not append the zone twice. Some hosts turn
status.acme.com into status.acme.com.acme.com when the zone is already selected.
