Network Guarantee: LuxSci guarantees that the network will be available 100% of the time in a given month, excluding scheduled maintenance. Upon experiencing downtime, LuxSci will refund the customer 5% of the monthly fee for each 30 minutes of downtime (up to 100% of customer's monthly fee for the affected servers). Network uptime includes functioning of all network infrastructure including routers, switches and cabling, but does not include services or software running on your server. Network downtime exists when a particular customer is unable to transmit and receive data and LuxSci records such failure in the LuxSci support ticket system or Rackspace records such a failure in the Rackspace trouble ticket system. Network downtime is measured from the time a LuxSci support ticket is opened by a customer to the time the server is once again able to transmit and receive data.

Infrastructure: LuxSci guarantees that the critical infrastructure systems, including power and HVAC, will be available 100% of the time in a given month, excluding scheduled maintenance. Upon experiencing downtime, LuxSci will refund the customer 5% of the monthly fee for each 30 minutes of downtime (up to 100% of customer's monthly fee for the affected servers). Critical infrastructure includes functioning of all power and HVAC infrastructure including UPSs, PDUs and cabling, but does not include the power supplies on customers' servers. Infrastructure downtime exists when a particular server is shut down due to power or heat problems and LuxSci records such failure in the LuxSci support ticket system or Rackspace records such a failure in the Rackspace trouble ticket system. Infrastructure downtime is measured from the time the customer opens a LuxSci support ticket regarding server downtime to the time the problem is resolved and the server is powered back on.

Hardware: LuxSci guarantees the functioning of all leased hardware components and will replace any failed component at no cost to the customer. Hardware replacement will begin once Rackspace identifies the cause of the problem. Hardware replacement is guaranteed to be complete within one hour of problem identification. In the event that it takes us more than one hour to replace faulty hardware, LuxSci will refund the customer 5% of the monthly fee per additional hour of downtime (up to 100% of customer's monthly fee for the server in question). Hardware is defined as the Processor(s), RAM, hard disk(s), motherboard, NIC card and other related hardware included under the server lease. This guarantee excludes the time required to rebuild a RAID array and the reload of certain operating systems and applications.

Each request in connection with this SLA must include the dates and times of the unavailability of customer's Services, a description of the perceived problem, and must be received by LuxSci within ten (10) business days after customer's Services were not available. If the unavailability is confirmed by LuxSci, credits will be applied within 30 days of LuxSci's receipt of customer's credit request.

Notwithstanding anything to the contrary herein, the total amount credited to customer in a particular month under this SLA shall not exceed the total dedicated hosting fees paid by customer for said month for the affected server(s).
