Diverse connections improve the robustness of your network by using different physical infrastructure to provide network services. Diverse connections build in redundancy and eliminate single points of failure.

{ productLong_0 } ({ productShort_0 }) simplifies the deployment of diverse connections by establishing diversity zones. A diversity zone is a group of devices at a single Megaport location. { productShort_0 }s in different diversity zones are physically separated on Megaport devices and connected to different devices.

During Megaport scheduled maintenance, no more than one diversity zone in a given metro will experience downtime at any time. Whenever possible, diversity zones in the same city have maintenance periods scheduled for different days.

Each { productShort_0 } indicates its diversity zone with either a red or blue icon.

## Selecting a diversity zone

When you select the location for your { productShort_0 }, you can select the diversity zone.

When you choose a diversity zone, the location results list will be filtered by that zone:

* **Auto (default)** -- This will show all locations where { productShort_0 } is available.
* **Red or Blue diversity zone** -- If you select Red or Blue diversity zone, only locations that have availability in that zone will be displayed.

| <InlineImage src="/images/snippets/diversity-auto.png" alt="Auto diversity zone." shadow={true} height={35} /> | Auto select diversity zone | Allow Megaport to allocate the diversity zone              |
|  <InlineImage src="/images/snippets/diversity-red.png" alt="Red diversity zone." shadow={true} height={35} />  | Red diversity zone         | Allocate the { productShort_0 } to the red diversity zone  |
| <InlineImage src="/images/snippets/diversity-blue.png" alt="Blue diversity zone." shadow={true} height={35} /> | Blue diversity zone        | Allocate the { productShort_0 } to the blue diversity zone |

### Auto diversity zone

If you choose the Auto diversity zone option, Megaport will select the zone to which your service is allocated.\
The following rules apply:

* If both diversity zones are available, one zone will be chosen.
* If only one zone is available, that zone will be chosen.
