# Technical support procedure
Yandex Cloud provides technical support under different service plans. You can choose the one that best suits you. The cost of paid technical support plans includes two components: fixed and supplemental. The supplemental part is calculated as a percentage of the cost of resources consumed during the month. For more information about the plans, see the [Pricing policy](pricing.md).
## Contacting support {#response-time}
Depending on your service plan, you can contact technical support using one of these methods:
* Using the [Support Center's](https://center.yandex.cloud/support) feedback form, 24/7.
* By email [cloud@support.yandex.ru](mailto:cloud@support.yandex.ru), 24/7.
* Using the chat, 24/7 for paid service plans and from 8 AM to 9 PM (UTC +3) on weekdays for the basic service plan.
The expected response time is shown in the table below.

Only a Yandex Cloud [user](../overview/roles-and-resources.md#users) can create a request in the support center. [Make sure](cloud-center.md#before-you-begin) you are making a request on behalf of the right organization. If your infrastructure has a production environment issue, select the  **Problem** request type with the _Critical_ priority.
We recommend creating a separate ticket for each issue. If your ticket describes multiple issues, technical support may create separate tickets for each one.
For more information on finding your request in Yandex Cloud, see [How do I find my request in Yandex Cloud](qa.md#how-to-find-request).

## What is not covered by technical support {#not-supported}
Yandex Cloud support engineers do not address the following:
* Software code development.
* Third-party software debugging.
* Support for [Yandex Cloud Marketplace](../marketplace/operations/users/quickstart.md#support) products published by vendors other than Yandex Cloud.
* Use of Advanced Yandex DDoS Protection.
* Yandex Tracker, Yandex Forms, Yandex Wiki.
* Operations with the MDB services within the [Yandex Cloud customer control zone](../overview/concepts/mdb-responsibilities.md#customer-responsibilities).
* Operations with Managed Service for Kubernetes within the [Yandex Cloud customer control zone](../overview/concepts/kubernetes-responsibilities.md#client-responsibility).
If the technical support cannot resolve your third-party software issue, contact the software vendor's support service. In some cases, contacting the vendor's support service requires a valid technical support contract with the vendor or its partners.
## How to change your service plan {#change-service-plan}
Before activating, deactivating, or modifying your technical support service plan, as well as changing the billing account from which the payment will be debited, make sure you have the following roles:
* [organization-manager.organizations.owner](../organization/security/index.md#organization-manager-organizations-owner) for a cloud organization where you need to change or activate a paid support service plan.
* [billing.accounts.admin](../billing/security/index.md#billing-accounts-admin) or higher for your billing account if it is not linked to this cloud organization. This role will be inherited if your account is linked to the organization. For more information about roles and the link between a cloud organization and a billing account, see [Organization](../billing/concepts/organization.md).
To change your Yandex Cloud technical support service plan:
1. On the [support home page](https://center.yandex.cloud/support) in Support Center, select **Service plans** in the left-hand panel.
1. In the **Service plans** window, you will see the billing account to be debited for paid technical support plans.
1. Change your plan:
* To switch to the **Basic** plan, click **Go**.
* To switch to the **Business** plan, click **Go**.
* To switch to the **Premium** plan, click **Send a request**.
If an organization with an activated support service plan uses resources paid from different billing accounts, the percentage part of the plan will be charged to each billing account according to the cost of consumed resources. The fixed part will be paid by only one account: the one specified when selecting the **Business** service plan. When you change your plan, you can choose the billing account to be used to cover the fixed portion of the plan. This option is only available to the organization owner. To change your billing account:
1. In the **Service plans** window, click **Edit** to select another account.
1. In the **Billing account** window, specify another account using one of the following methods:
* Select an account from the list.
* Create a new account.
Service plan upgrades are effective immediately; downgrades take effect on the first day of the following month. For information on current service plans and examples of how to calculate your costs, see [Pricing policy](pricing.md).
