The list of regions, availability zones and pools can be viewed in the [Selectel Infrastructure] table(/control-panel-actions/infrastructure.mdx).
Bandwidth for cloud servers on private networks can be increased to 10 Gbps — create a ticket.
The speed on a port may drop dramatically, for example, to 0.1 Gbps if the associated IP address is blocked by Selectel security. To increase the speed, create a ticket.
Examples of networks
Internet access
Cloud servers can be connected to a private network without Internet access and can be configured to access the Internet via routers and public IP addresses.

Private network and bastion host
A Bastion host is a host on a network that is a gateway or proxy for all other servers. Such a host is available at an external address and communicates with the rest of the servers over a private network.

Public network
All servers on the public subnet have access to the Internet. Servers communicate with each other through public interfaces.

Load balancer and bastion host
A load balancer can be added to the bastion-host scheme. The Bastion host is used to access the private network and manage the infrastructure, while the balancer performs proxying of requests.

Selectel Global Router
You can use Selectel global router (formerly L3 VPNs) to organize network connectivity between:
- cloud servers in different pools — including different projects and accounts;
- or cloud servers and other services — such as dedicated servers.
You can only add, rename or delete networks and subnets in Control Panel under Network Services → Selectel Global Router.
Global router networks that belong to the cloud platform can be viewed under Cloud Platform → Networks — they have the tag Global Router
.
Cloud servers from the global router network can be connected to the Internet via a public IP address.
