Enabling and disabling availability zones

If you do not have the Yandex Cloud CLI installed yet, install and initialize it.

By default, the CLI uses the folder specified when creating the profile. To change the default folder, use the yc config set folder-id <folder_ID> command. You can also set a different folder for any specific command using the --folder-name or --folder-id parameter.

1. See the description of the availability zone disable command for a network load balancer:

   yc load-balancer network-load-balancer disable-zones --help
   

2. Get a list of all network load balancers in the default folder:

   yc load-balancer network-load-balancer list
   

   Result:

   +----------------------+-------------+-------------+----------+----------------+------------------------+--------+
   |          ID          |     NAME    |  REGION ID  |   TYPE   | LISTENER COUNT | ATTACHED TARGET GROUPS | STATUS |
   +----------------------+-------------+-------------+----------+----------------+------------------------+--------+
   | ds70q425egoe******** | my-balancer | ru-central1 | EXTERNAL |              1 | enpakget56sr********   | ACTIVE |
   |                      |             |             |          |                | enpakf7vhj2l********   |        |
   | fw7fh46bnsge******** | my-nlb2     | ru-central1 | EXTERNAL |              1 | sn5u68knmswe********   | ACTIVE |
   +----------------------+-------------+-------------+----------+----------------+------------------------+--------+
   

3. Disable one or more availability zones using the following command:

   yc load-balancer network-load-balancer disable-zones \
     <load_balancer_name_or_ID> \
     --zones=<zone_1_ID>,[<zone_2_ID>] \
     --duration=<duration>
   

   Where:

   • --zones: Availability zone IDs.
   • --duration: Duration, from 1m to 72h. No value stands for unlimited duration. If zones are provided as a list, they all will be disabled for the specified period.

To disable two zones for a load balancer, list them separated by commas:

yc load-balancer network-load-balancer disable-zones ds70q425egoe******** \
  --zones=ru-central1-b,ru-central1-d

Result:

id: ds70q425egoe********
...
disable_zone_statuses:
  - zone_id: ru-central1-b
  - zone_id: ru-central1-d

To disable a single availability zone for 30 minutes, use the --duration parameter:

yc load-balancer network-load-balancer disable-zones ds70q425egoe******** \
  --zones=ru-central1-b \
  --duration=30m

Result:

id: ds70q425egoe********
...
disable_zone_statuses:
  - zone_id: ru-central1-b
    disabled_until: "2025-06-06T04:10:02.679608678Z"

You can extend the zone lock by running the above command with the --duration parameter once again for the same zone.

If you do not have the Yandex Cloud CLI installed yet, install and initialize it.

By default, the CLI uses the folder specified when creating the profile. To change the default folder, use the yc config set folder-id <folder_ID> command. You can also set a different folder for any specific command using the --folder-name or --folder-id parameter.

1. See the description of the availability zone enable command for a network load balancer:

   yc load-balancer network-load-balancer enable-zones --help
   

2. Get a list of all network load balancers in the default folder:

   yc load-balancer network-load-balancer list
   

   Result:

   +----------------------+-------------+-------------+----------+----------------+------------------------+--------+
   |          ID          |     NAME    |  REGION ID  |   TYPE   | LISTENER COUNT | ATTACHED TARGET GROUPS | STATUS |
   +----------------------+-------------+-------------+----------+----------------+------------------------+--------+
   | ds70q425egoe******** | my-balancer | ru-central1 | EXTERNAL |              1 | enpakget56sr********   | ACTIVE |
   |                      |             |             |          |                | enpakf7vhj2l********   |        |
   | fw7fh46bnsge******** | my-nlb2     | ru-central1 | EXTERNAL |              1 | sn5u68knmswe********   | ACTIVE |
   +----------------------+-------------+-------------+----------+----------------+------------------------+--------+
   

3. Enable one or more availability zones:

   yc load-balancer network-load-balancer enable-zones \
     <load_balancer_name_or_ID> \
     --zones=<zone_1_ID>,[<zone_2_ID>]
   

   Result:

   id: ds70q425egoe********
   ...
   allow_zonal_shift: false
   disable_zone_statuses:
   

If you do not have the Yandex Cloud CLI installed yet, install and initialize it.

By default, the CLI uses the folder specified when creating the profile. To change the default folder, use the yc config set folder-id <folder_ID> command. You can also set a different folder for any specific command using the --folder-name or --folder-id parameter.

To check if there are any disabled zones and whether a lock period is set, run the following command:

yc load-balancer network-load-balancer get \
  <load_balancer_name_or_ID>

Result:

id: ds70q425egoe********
...
disable_zone_statuses:
  - zone_id: ru-central1-b
  - zone_id: ru-central1-d
    disabled_until: "2025-06-06T04:10:02.679608678Z"
