High Availability Registry Operator will conduct its operations using network and geographically diverse, redundant servers (including network-‐level redundancy, end-‐node level redundancy and the implementation of a load balancing scheme where applicable) to ensure continued operation in the case of technical failure (widespread or local), or an extraordinary occurrence or circumstance beyond the control of the Registry Operator. Registry Operator’s emergency operations department shall be available at all times to respond to extraordinary occurrences.
EPP service availability Refers to the ability of the TLD EPP servers as a group, to respond to commands from the Registry accredited Registrars, who already have credentials to the servers. The response shall include appropriate data from the Registry System. An EPP command with “EPP command RTT” 5 times higher than the corresponding SLR will be considered as unanswered. If 51% or more of the EPP testing probes see the EPP service as unavailable during a given time, the EPP service will be considered unavailable.
Funding Availability This Contract is at all times subject to state appropriations. The Department makes no express or implied representation or guarantee of continued or future funding under this Contract. The Department has, as of the date of the execution of this Contract, obtained all requisite approvals and authority to enter into and perform its obligations under this Contract, including, without limitation, the obligation to make the initial payment or payments required to be made under this Contract on the date or dates upon which such initial payment or payments may otherwise be disbursed during the current contract period, (i.e., Sept ember 1, 2015, through August 31, 2017). The Grantee acknowledges the Department’s authority to make such payments is contingent upon the Texas Legislature's appropriation to the Department of sufficient funds and the availability of funds to the Department for such purpose. If the State of Texas or the federal government terminates its appropriation through the Department or fails to pay the full amount of the allocation for the operation of any grant or reimbursement program hereunder , or the funds are otherwise unavailable, the Department may immediately and without penalty reduce payments or terminate this Contract, in whole or in part. Upon termination of the Contract or reduction of payments, the Grantee shall return to the Department any unexpended funds already disbursed to the Grantee. Neither the Department nor the State of Texas shall incur liability for damages or any loss that may be caused or associated with such termination or reduction of payments. The Department shall not be required to give prior notice for termination or reduction of payments.
DNS service availability Refers to the ability of the group of listed-‐as-‐authoritative name servers of a particular domain name (e.g., a TLD), to answer DNS queries from DNS probes. For the service to be considered available at a particular moment, at least, two of the delegated name servers registered in the DNS must have successful results from “DNS tests” to each of their public-‐DNS registered “IP addresses” to which the name server resolves. If 51% or more of the DNS testing probes see the service as unavailable during a given time, the DNS service will be considered unavailable.
