⚙️ Facility Highlights

Data Center Footprint:

A1 Hrvatska publicly markets A1 Business Solutions data center services and colocation from its own data center environment in Croatia. Its business materials describe a modern A1 data center used for colocation and cloud services, while company media releases state that A1 opened a new data center investment intended to support growing demand for cloud services and colocation in Croatia. Publicly accessible reviewed sources clearly support an A1 operated domestic data center footprint, but they do not provide a clean current public portfolio list of multiple named colocation facilities on the business service pages.

A1 Hrvatska positions this infrastructure for business continuity, enterprise cloud usage, and domestic hosting. The colocation and virtual infrastructure pages both frame the environment as suitable for production, test, development, backup, and disaster recovery use cases, with the infrastructure operated under the same security rules, tools, and operational center used for A1’s own information infrastructure.

Facility Design & Infrastructure:

A1 Hrvatska’s colocation page publishes substantial facility detail. The service includes 19 inch server cabinet environments, Internet access from 50 Mbps/50 Mbps, included nominal power from 100W to 4000W depending on package, redundant internet connections, hot and cold aisle temperature control, 16A or 32A PDUs, monthly power monitoring, UPS and generator backed power, redundant cooling, smoke and fire detection, Novec 1230 gas fire suppression, and the possibility of 10G links. The same page also states that A1’s data center is carrier neutral.

Deployment options are publicly described from 1U up to quarter, half, and full cabinets, and A1 also publishes a private cage option. The FAQ states that a private cage is a separately enclosed space with electrically locked doors and floor to ceiling partitions, while the product page notes that independent access is available for quarter, half, or full cabinet customers, subject to prior notice. A1 also publishes a dedicated work room inside the data center for working on equipment without being physically inside the main equipment area.

Service Portfolio Overview:

A1 Hrvatska publicly markets colocation, A1 Cloud IT virtual infrastructure, A1 Backup as a Service, A1 Exoscale cloud compute, SD WAN, Biz IP VPN, Biz Ethernet, internet access, and multiple managed security services as part of its business solutions portfolio. The virtual infrastructure page explicitly describes A1 Cloud IT as Infrastructure as a Service, while the backup page explicitly describes A1 Backup as a Service and a managed backup variant.

The cloud portfolio also includes disaster recovery related positioning and object storage under A1 Exoscale. The virtual infrastructure page explicitly lists BaaS and DRaaS as part of what customers can place on A1’s infrastructure, while the A1 Exoscale page describes a cloud compute platform with object storage, SSD cloud servers, and EU based data location.

🔐 Security & Compliance

Infrastructure Resilience:

A1 Hrvatska’s colocation page states that its data center is positioned around Tier III design and construction criteria and references SLA 99.982% for critical data center infrastructure including power, cooling, and Internet links. The same page also publishes redundant internet connectivity, UPS and generator backed power, redundant cooling, and protected cabinet environments.

A1’s virtual infrastructure and SD WAN materials reinforce this resilience posture by positioning the environment for production, development, backup, and disaster recovery, and by describing constant monitoring of link conditions with dynamic traffic steering in SD WAN. In November 2024, A1 Hrvatska also announced that its data center had passed recertification and received a Tier III Facility certificate from Uptime Institute.

Physical & Logical Security:

The colocation page states that customers can choose supervised or independent access to ICT equipment depending on the package, and that server cabinet doors in most colocation packages are protected by anti burglary locks. The private cage description adds electrically locked access and floor to ceiling separation. A1 also publishes 24/7/365 remote hands and eyes support from its specialist team.

For logical and operational security, A1 Hrvatska publicly markets Firewall as a Service, Anti DDoS protection, and a Security Operations Center. The SOC page states 24/7 monitoring of endpoints, threat detection, and regular reporting, while the firewall page says A1 experts can handle installation, configuration, and consultation.

Compliance & Standards:

A1 Hrvatska’s colocation page explicitly references ISO/IEC 27001, ISO/IEC 9001, ISO/IEC 27017, and ISO/IEC 45001 for the data center environment. Its corporate ethics page also lists ISO 45001:2018, ISO 9001:2015, ISO 14001:2015, ISO 27001:2013, ISO 27017:2015, ISO 22301:2019, PCI DSS Certificate of Compliance, and Tier III Certificate among its certifications and ratings.

A1 Hrvatska also published that its A1 data center received PCI DSS certification and, separately, a Tier III Facility certification / recertification from Uptime Institute. These are publicly supported and directly relevant to its data center operation. SOC reports are Not publicly listed in the reviewed sources.

🌐 Connectivity & Carrier Access

Carrier Neutrality:

A1 Hrvatska explicitly states on its colocation page that the A1 data center is carrier neutral. The same page also states that internet access service can be selected according to customer preference, which supports third party connectivity choice within the colocation environment.

The reviewed sources do not clearly publish a branded meet me room product page or a broad alternate carrier partner catalog, but the published carrier neutral wording and customer choice of internet access clearly support a carrier neutral colocation model.

Network Capabilities:

A1 Hrvatska publicly markets Biz Ethernet, Biz IP VPN, business internet, SD WAN, and multiple security overlay services. Biz Ethernet is described with symmetric speeds from 0.5/0.5 Mbps up to guaranteed 10/10 Gbps, while Biz IP VPN is described as an A1 Business Solutions data network connecting into the customer network at Layer 3.

Its SD WAN page states that the service supports centralized orchestration, dynamic traffic steering, integrated security, and simultaneous use of multiple access links across technologies such as fiber, mobile network, and DSL. The colocation page also adds support for 10G links and redundant internet connections.

Connectivity Use Cases:

The reviewed service portfolio supports colocated enterprise equipment connected through carrier neutral access, customer chosen internet access, and A1 operated business networking services. This aligns with customers seeking resilient hosted ICT environments combined with domestic telecom connectivity.

The same portfolio also supports hybrid style infrastructure patterns where customers use A1 Cloud IT, backup, and disaster recovery related services together with branch or multi site networking through SD WAN, Ethernet, and IP VPN. Security overlays such as Firewall as a Service, Anti DDoS, and SOC further support business critical and regulated IT environments.
