2.   Definitions

This Web Site Availability Service Level Agreement (“SLA”) applies to you ("Customer") if you have ordered a Virtual Private Server (“VPS”) hosting or a Virtual Machine ("VM") account services from ServerNest GmbH (the "Services") and your account is current (i.e., not past due) with ServerNest GmbH.

As used herein, the term “Server Availability" means the percentage of a particular month (based on 24-hour days for the number of days in the subject month) that the content of customer's Web site is available for access by third parties through the Internet, as measured by ServerNest GmbH, provided that Customer has established connectivity.

3.   Service Level

Network availability:

Our guarantee is that our Network will be available to Customers free of Network Outages that render 100% packet loss, 99.9% of each calendar month. ServerNest GmbH will replace faulty network equipment within 6 hours.

DNS Servers:

Our guarantee is to operate at least two (2) DNS servers running on different Hardware node located in different datacenter. DNS servers will be available to Customers 99.9% of each calendar month.

Virtual Server Availability:

ServerNest GmbH maintains a set of cold-standby spare servers, which are used to replace a server with a hardware failure. Our guarantee is that Customer’s VPS will be available within our Network, 99.9% of each calendar month. ServerNest GmbH will migrate Customer’s VPS to a spare Hardware Server should the Hardware node hosting the VPS be defective (e.g.: in the event of a hard disk failure in the RAID1 mirroring system) or should maintenance work be applied it (e.g: OS patch). In some cases, the spare server will not have the same hardware specifications as the original server (e.g. smaller hard disk or other CPU). In this case, the original server will be repaired and reinstated. ServerNest GmbH will contact the customer to plan and execute this intervention. In some cases ServerNest GmbH may decide to replace defective hardware (ex. Hard disks) without consent of the customer if the intervention is time critical or if the defect has a severe impact on the service.

ServerNest GmbH takes responsibility for VPS availability within their network, however, we cannot be held liable for upstream problems, outside of our network.

Subject to Sections 4 and 5 below, if the Server Availability of customer is less than 100%, ServerNest GmbH will issue a credit to customer in accordance with the following schedule, with the credit being calculated on the basis of the monthly service charge for the affected Services:
Server Availability

Credit Percentage
99.9 to 100%

98% to 99.8%

95% to 97.9%

90% to 94.9%

89.9% or below


If there are multiple down times in the same service period, the time is added together. e.g. 2 down times each lasting 2 minutes each would count as 4 minutes of downtime in a month giving credit of 10%.
