# DNS Flush Runbook
|
|
|
|
## Symptoms
|
|
|
|
- DNS resolutions return stale IPs.
|
|
- Users report that a site "works on some machines and not on others".
|
|
- Recent DNS changes are not propagating.
|
|
|
|
## Diagnosis
|
|
|
|
1. Check the local cache with `ipconfig /displaydns` or `resolvectl statistics`.
|
|
2. Confirm the upstream resolver is responding.
|
|
3. Run the `dns-flush` webhook on the affected machine.
|
