UltraHosting Service Level Agreement

UltraHosting cares about our customers enough to commit that their web sites and applications stay running all the time. We call this our UltraSupport™. Our commitment is backed by this Service Level Agreement

Power and Cooling Availability.

Ultrahosting guarantees that its power and Cooling systems will be available 100% of the time excluding Planned Maintenance. Please note that outages due to power supply issues on a customer server are covered by the hardware repair and replacement section.

Network Availability

Ultrahosting guarantees that the UltraHosting network will be available 100% of the time, excluding Maintenance. "Network Downtime" is defined as an inability to transmit and receive data caused by failure of core network equipment managed and owned by Ultrahosting, excluding Maintenance.

IP Address Policy

All servers are provisioned with one usable IP address. If customers require additional IP addresses, they must request additional IP addresses by completing an IP address request form (form available at http://bit.ly/175u0xD). The form is to be sent to support to be processed.

IP addresses are strictly controlled by ARIN and your request is subject to ARIN guidelines and approvals. Additional charges will apply for approved requests of more than 8 (5 usable) IP addresses. For more information, please visit the official ARIN web site at http://www.arin.net.

Server Hardware Replacement

Ultrahosting will replace or repair any Ultrahosting supplied server at no cost to the customer within 4 hours.

This time frame is based on the customer informing Ultrahosting of the hardware issue, and arranging a maintenance window with the customer. The time to replace or repair does not include the time required to rebuild a RAID array or the reload of the operating systems and applications or changes to dedicated hardware during maintenance, as defined below. The customer is responsible to reload any customer installed applications and data.

In order to claim Credits, Customer must open a support ticket. The Customer may only claim one credit per incident and the credits for one month may not exceed the monthly billing amount.

Credits will be applied to accounts that are past-due or for accounts that are cancelled before the conditions for payment of the Credit are met. Credits will not be applied against past due balances or cancelled accounts.
