FAQ

How do I contact support?

Registered clients open a support ticket from the client area:

  1. Sign in at https://my.kastervo.cloud/clientarea.
  2. Select “Support Tickets” in the menu on the left.
  3. Select “Create new”.
  4. Choose the department you need and describe your request.

Every account includes basic, best-effort support, handled in queue order during operational hours. Anything beyond that, such as monitoring, software installation, backups, security packages or faster response, is a paid support plan quoted for your setup. Support plans cover infrastructure and OS-level tasks, and we aren’t obligated to support third-party or custom software such as an ERP.

Which payment methods do you accept?

We accept PayPal and bank transfer.

Do you sell to individuals?

No. We sell KASTERVO services only to businesses and the public sector.

How do I sign in to my account?
How do I connect to my KASTERVO Virtual Private Cloud (KVPC)?

Over VPN. You set up and manage the VPN connections yourself, using IKEv2, OpenVPN, IPsec or WireGuard.

Which operating systems can I install on a KASTERVO Compute Instance (KCI)?

We provide templates for:

  • Windows Server 2025 Datacenter
  • Debian 13

To use a different operating system, open a support ticket and request it.

Can I reduce the storage on a KASTERVO Compute Instance (KCI)?

No, because shrinking a storage volume can cause data loss. Instead, you can move your workloads to a new KCI with a smaller volume.

How many VLANs can I add to my KVPC?

As many as you need. We don’t limit the number of private VLANs on a KVPC, and you choose the VLAN IDs.

Do you charge for private VLANs or private IP addresses?

No. We don’t charge for internal VLANs or private (RFC 1918) IP addresses.

Do you charge for egress or ingress traffic?

No. We don’t charge for traffic in either direction. You pay a fixed monthly price per unit, whatever your usage.

How do I cancel my subscription?

Request cancellation from your account at https://my.kastervo.cloud/.

How long do you keep my data after I cancel?

If you cancel your subscription, we delete your data within 24 hours.

If you let your subscription expire, we delete your data 30 days after the expiry date.
