# General questions about Yandex IoT Core

{% note warning %}

Yandex IoT Core is no longer available to new users. 

Current users can create resources until November 1, 2026. Afterwards, the service will go read-only and cease to operate on December 1, 2026. For more information on the timing and procedure, see [Service shutdown](../sunset.md).

{% endnote %}

#### Can I get logs of my operations in Yandex Cloud? {#logs}

Yes, you can request information about operations with your resources from Yandex Cloud logs. Do it by contacting [support](https://center.yandex.cloud/support).

#### How do I test message delivery? {#check-message-was-delivered}

To make sure the MQTT server has received a [sent message](../operations/publish.md), specify additional debugging parameters in the send message command. As a result, you will get a detailed command output.

To test Yandex IoT Core, use messaging and device subscription at the same time. If you subscribe a [registry](../concepts/index.md#registry) to a [device topic](../concepts/topic/devices-topic.md) and send a message to this topic, the registry will receive the message.

For more information, see [Testing message delivery](../tutorials/message-delivery-check.md).
