What to change
Ask the hosting owner to distinguish restored origin content from cached public responses. Record the affected addresses and any available cache evidence, then apply the site's controlled invalidation approach if appropriate. Test through fresh external requests and a returning session rather than relying only on the restoration operator's browser. The incident remains partly unresolved until the agreed public sample receives the corrected behaviour or the remaining scope is clearly communicated.
A worked example
Illustrative example
Illustrative test: Independent fresh requests receive the restored page instead of the earlier cached failure. After a rollback, the restored source may be correct while a public delivery layer still serves an earlier error for one guide. The hosting owner compares those responses and applies the approved refresh or expiry plan. Independent fresh requests and a returning session are checked afterwards. The incident record keeps any remaining public scope visible, avoiding repeated identical deployments that do not address the layer actually supplying the stale response.
What this means for your practice
A restored version may be correct at the host while some visitors still receive a saved faulty response from a delivery layer. Ask the hosting owner to compare the restored source with the public responses for the affected addresses. They should apply the site's approved refresh or expiry approach where needed, then check fresh external requests and a returning session. Repeatedly publishing the same files may not address that saved-copy condition. Keep any remaining affected scope visible in the incident record. The practice's recovery decision should reflect what its visitors now receive, not solely what the restoration operator sees in a privileged or unusually fresh browser.
How to check the result
The public recovery evidence covers the delivery layer visitors actually use.
A mistake to avoid
Repeatedly redeploying identical files may not address the cache condition.
