Route53 运行状况检查在端点关闭时显示正常
Route53 health check shows OK while the endpoint is down
我不确定这怎么可能，但我设置了一个 Route 53 健康检查，如果我们的端点出现故障，会发出电子邮件警报。
它肯定是宕机了，因为托管它的 EC2 已关闭。
❯ telnet foo.io 443
Trying 18.18.18.18...
telnet: connect to address 18.18.18.18: Operation timed out
telnet: Unable to connect to remote host
检查器是否缓存了一些东西？虽然我们没有在两者之间使用任何东西，但它应该直接命中 EC2。
我认为您已禁用健康检查
这就是 doc states
Stops Route 53 from performing health checks. When you disable a health check, Route 53 stops aggregating the status of the referenced health checks.
After you disable a health check, Route 53 considers the status of the health check to always be healthy. If you configured DNS failover, Route 53 continues to route traffic to the corresponding resources.
也许这就是你看到它的原因通过
