Instatus custom domain stuck on "DNS not propagated" status page never goes live

TL;DR

Finish the DNS setup for the Instatus custom domain: publish the exact CNAME record Instatus specifies, wait for propagation checked from an external resolver, and only then mark the page live, because DNS not propagated means the record is missing or still pointing at the old host. Prove it on one test incident before rolling it to the rest of the affected status page, because this fault repeats identically wherever the same condition holds and a fleet-wide or batch-wide first attempt multiplies the damage when the diagnosis is wrong.

Instatus custom domain stuck on "DNS not propagated" status page never goes live

Use this when

• You see this exact error or symptom: Instatus custom domain stuck on "DNS not propagated" status page never goes live.
• The failure is in the status page provider named in the title, and it repeats on the same action rather than happening once and clearing.
• Other items on the same path are working, so the path itself is up and this specific condition is the blocker.

Not for this skill when

• A different error code, message, or tool is involved. Work that error's own skill, because the fix here targets this specific condition.
• The whole service or platform is down. Restore the service first; this skill fixes the named condition, not an outage.
• You cannot identify one affected item to test on. Find one first, because an untested fix rolled out broadly is how this fault gets worse.

Steps

1. Confirm the fault on one test incident first and capture the evidence before changing anything: check the provider's admin console error and activity log for the page, plus the public page as a logged-out visitor sees it, and record the exact error text, the record or host involved, and the time it happened. Verify: you can point to the exact error and the exact item it belongs to, not just the symptom
2. Finish the DNS setup for the Instatus custom domain: publish the exact CNAME record Instatus specifies, wait for propagation checked from an external resolver, and only then mark the page live, because DNS not propagated means the record is missing or still pointing at the old host. Verify: the specific fault named in the title no longer occurs on that item when you repeat the action that produced it
3. Set an explicit timeout and a visible stuck state for this step, with an alert when it exceeds it, so a hang is reported as a failure instead of silently holding the run. Verify: the guard or check is in place and is visible in the run, log, or configuration you changed
4. Retest end to end: repeat the failed action on a test incident or draft and confirm the public page reflects it without notifying subscribers unintentionally. Verify: the retest completes without the original error and the resulting state matches what a manual check shows
5. Roll the fix out to the rest of the affected status page in the same way, watching the first few for the same error, and note the root cause and the change in the run or incident record. Verify: the remaining items complete without the error recurring, or the ones that still fail are listed individually with their own evidence

Why it happens

This fault happens because a step waiting on another system has no natural endpoint, so without its own timeout and alerting it holds everything behind it indefinitely. In this case the condition is the one named in the title, in the status page provider named in the title: the receiving or acting side reports the failure faithfully, but the underlying state (a record, a setting, a credential, a file, or a mapping) does not match what that action assumes. Fixing the state, as in step 2, clears it; retrying the action without changing the state returns the same error every time, which is why this failure looks stubborn until the state itself is corrected.
