How long are stale objects served by CloudFront when an origin is unavailable?
When an origin is unavailable, CloudFront will serve the requested object from its cache even if it's stale. If the origin never comes back up, how long will CloudFront continue to serve the stale object?
CloudFront will continue to serve stale content if the origin is unavailable. If the origin remains unavailable for a long time, or never comes back, CloudFront may evict the object if it is seldom used. There are no specific guidelines on how long it may be before the eviction happens.
