Service Specification Domains & DNS

This English version is provided for convenience only. The German version is legally binding; in the event of any discrepancy between the two versions, the German version shall prevail.

1. Brief description

centron Domains & DNS provides a combined service for the registration, management and technical resolution of domain names.

The service comprises both the provision and management of internet domains and the management of DNS zones and DNS records. DNS resolution takes place via a highly available infrastructure and ensures that domain names are reliably translated into IP addresses.

Management takes place via the centron portal and via corresponding application programming interfaces (APIs).

2. Key features

centron Domains & DNS offers an integrated platform for managing domains and DNS with the following characteristics:

• Registration and management of domains with the relevant registries (registration body / allocation authority / Network Information Center)
• Management of DNS zones and DNS records
• Use of a highly available DNS infrastructure with globally distributed resolution
• Support for Anycast DNS to optimise response times and availability
• Protection mechanisms against overload situations and DoS attacks (denial-of-service attacks)
• Option to use the service as a primary or secondary DNS provider
• Use with own domains or with subdomains provided

The platform enables central management of domain and DNS configurations in conjunction with other cloud services.

3. Service plans

centron Domains & DNS is provided as a combined service.

For domains, billing and configuration depend on:

• Top-level domain (TLD)
• Registration body (registry)
• Term of the domain

For DNS, the configuration is determined dynamically on the basis of usage, in particular:

• Number of DNS zones
• Number of DNS records per zone

Classification into service tiers takes place automatically on the basis of actual usage.

4. Metrics

Billing is carried out separately for domain services and DNS services:

Domains:

• Billing per registered domain, generally on a monthly basis
• Prices depend on TLD and registry

Additional costs may arise from add-on services or special domain extensions.

5. SLA specifics

The following applies to the DNS service:

The service is available if DNS resolution can be performed successfully for defined test records.

Availability is governed by the general SLA provisions of the centron cloud infrastructure.

No separate SLA commitments are made for domain registrations themselves, as these depend on external registries and allocation authorities.

6. Backup

DNS zones are backed up automatically according to a schedule defined by centron.

This schedule cannot be adjusted by the Customer. In addition, customers have the option of exporting and restoring DNS zones manually via the portal or APIs.

Domain-related data (e.g. registration data) is backed up as part of the respective registry processes.

7. Additional terms

The Customer is responsible for the selection, registration and use of its domains. There is no entitlement to the allocation of specific domain names.

Registration is subject to availability and to the policies of the respective allocation authorities (registries). centron gives no guarantee for the allocation or permanent availability of a domain.

The Customer is responsible for all content accessible under its domains and for compliance with all statutory and regulatory requirements.

When using the DNS service, the Customer is responsible for the configuration of its DNS zones and DNS records. Incorrect configurations may result in services being unreachable and fall within the Customer’s area of responsibility.

DNS data is publicly accessible on the internet. The Customer must ensure that no sensitive data or data requiring protection is published in DNS records.

centron is entitled to make technical changes to the DNS infrastructure, in particular to name servers, routing or Anycast structures, provided that this does not significantly impair the quality of the service.

centron is entitled to block individual domains or DNS zones temporarily or permanently if:

• statutory provisions are violated
• third-party rights are affected
• the stability of the infrastructure is endangered

In the event of incidents or security incidents, the Customer is obliged to cooperate without undue delay and to take suitable measures to remedy them.

In the event of legal infringements or third-party claims, the Customer shall indemnify centron against such claims insofar as they are attributable to use by the Customer.
