If the power goes out
The UPS picks up the load at once, and the diesel generators then start automatically. Power arrives over dedicated medium-voltage lines, and two independent feeds run into the rack.
The second Warsaw site: the NASK data center
PL-2 is the data center of the operator NASK S.A., the second Host4Biz site, in another part of Warsaw and with engineering systems of its own.
- The data stays in EU jurisdiction
- Power feeds independent of PL-1
- Our own redundant link to PL-1

Where the Host4Biz infrastructure stands
PL-2 is the data center of the operator NASK S.A., holding part of our Warsaw infrastructure. It is a site separate from PL-1, with engineering systems of its own.
1,000 m² across four independent server chambers are set aside for equipment. The Host4Biz infrastructure runs here continuously.
The level of the site is confirmed by an independent audit against an international standard: both the design and the built facility are certified.
What protects your data
Several independent lines stand between a city failure and your server.
Temperature in the halls
Precision cooling runs in an N+1 layout: one air conditioner failing does not touch the hall. Cold and hot aisles help hold temperature and humidity all year round.
If a fire starts
Early smoke detection catches ignition before open flame. Gas suppression works without water and without damage to equipment, and fire compartments contain the fire.
Who can come in
Physical security is arranged in three zones. The site is watched around the clock by the relevant NASK services.
If the network drops
The network infrastructure of the site is redundant. On our side we duplicate the links in the racks and use paired switches, so that one device failing does not break the network.
Who has checked this
ANSI/TIA-942-B Rated-3 is confirmed for the architectural, telecommunications, electrical and mechanical parts, for the design and for the built facility alike.
The Host4Biz network on the second Warsaw site
PL-2 is a separate site in another part of Warsaw, and it is part of the shared Host4Biz infrastructure.
Our own hardware
The Supermicro servers here are our own. Their configuration, load and spare performance are in the hands of the Host4Biz team.
Duplication at the rack
Connectivity reaches the servers over two paths, and the network switches are joined into pairs. One failure should not cut the site off the network.
A fast internal fabric
Between the racks the network runs at 100 Gbps. The external links terminate in the Host4Biz autonomous system, so we manage the traffic routes ourselves.
The second site in the shared network
PL-2 is linked to PL-1 by redundant Host4Biz fiber. The two sites stay physically independent, while traffic between our equipment travels over an internal link and never touches the public internet.
Why two sites in one city
What the second site is for, rather than simply more racks in the first.
Two independent sites
The buildings, the power feeds, the engineering teams and the contractors differ between the two locations. That way the Host4Biz infrastructure does not depend on one shared engineering loop.
The link between the sites
Our own redundant fiber connects the sites, so a project can be laid out across one city and one jurisdiction.
Both sites in service
The Host4Biz infrastructure runs on both sites continuously, and neither of them is held in reserve.
What you can order with placement in Warsaw
You choose the service and the Polish location. If a physical server needs a particular site, PL-1 or PL-2, agree it with support before ordering.
Linux VPS
Five NVMe plans with KVM and root access. They fit websites, stores, CRM, APIs and working services.

About where Host4Biz servers stand and about the second Warsaw site.
Can I choose whether my physical server goes to PL-1 or PL-2?
Yes. If a physical server has to stand at a particular site in Warsaw, write to support before ordering and we will agree on placement in PL-1 or PL-2.
What does ANSI/TIA-942-B Rated-3 mean?
Rated-3 means the data center infrastructure can be serviced and repaired without stopping the equipment. The rating is issued by an independent auditor, and at this site it was obtained both for the design and for the built facility — two separate checks, the second confirming that what was built matches the design.
Why does Host4Biz keep two sites in Warsaw?
Two sites with different operators give us separate engineering loops in one city. That does not automatically switch redundancy on for a service: the architecture of a project and the options it needs are chosen separately.
Does redundancy between PL-1 and PL-2 have to be ordered separately?
Yes. Both sites can be used for redundancy, replication or disaster recovery. Support will help choose the right service and placement scheme.
