We are using Kernel-based Virtual Machine (KVM) which is an open source virtualization technology built into Linux®. Specifically, KVM lets you turn Linux into a hypervisor that allows a host machine to run multiple, isolated virtual environments called guests or virtual machines (VMs).

KVM converts Linux into a type-1 (bare-metal) hypervisor. All hypervisors need some operating system-level components—such as a memory manager, process scheduler, input/output (I/O) stack, device drivers, security manager, a network stack, and more—to run VMs. KVM has all these components because it’s part of the Linux kernel. Every VM is implemented as a regular Linux process, scheduled by the standard Linux scheduler, with dedicated virtual hardware like a network card, graphics adapter, CPU(s), memory, and disks.

Sure, you can just install new kernel version or compile your own build. Reboot your VPS and safely watch the boot or rollback using our VNC console in the clientarea

We are using Supermicro TwinPro 4 nodes servers with Xeon Gold CPUs, each node is connected to clustered HP Enterprise storage via redundant high-speed SFP cables. Each server is connected via multiple uplinks to our Core HPE Aruba switches. 
All elements are redundant: Power supply on servers, all SFP/ethernet cables, all switches/firewalls/routers as well as uplinks and power supply/UPSs/generators in the Tier IV datacenter.

Currently we offer VPS and shared hosting service in our datacenter located in Czech Republic (our AS213354), heart of Europe with best routing to all EU countries. Soon we will offer it in Singapore (our AS50935) and Ukraine (our partner`s AS48031). Dedicated servers are offered in Ukraine and Czech Republic. 
We manage about 12 000 IP addresses worldwide

By default during the order you can select up to 32 IPv4 addresses. If you need more please contact us

Yes. VPSs within the same datacenter can be connected into the service page. Contact us to learn more.
