This Guaranteed 100% Uptime Service Level Agreement (this "SLA") is a binding agreement between ZZ Servers and Customer and supplements the Terms of Service executed between the parties, posted at http://www.zzservers.com/about/policy/tos/ (the "Agreement").

This SLA covers the following elements of the Service:

  • Network Performance
  • Hardware Replacement
  • Support Response Time
  • Domain Name Services
  • Power Availability & Performance
  • Cooling & Environment
  • Server Power Cycling
  • Physical Security
  • 24 x 365 On-Site Engineering

* "Uptime" refers to network performance, as defined in Article II.B below.

I. REMEDIES FOR SERVICE FAILURE

A. 100% Guaranteed

(1) If the Service does not achieve the performance levels described in Articles II through X below ("Failure"), ZZ Servers will provide Customer with a 100% Service Credit (as defined below), pursuant to the provisions, requirements, and limitations of this SLA, including Articles XI through XIII.

(2) A "100% Service Credit" is a credit equivalent Customer's Service Fees for the duration of the Failure, applied against fees for the Service Element (as defined below) subject to the Failure. (For example, where applicable pursuant to this SLA: a Failure lasting seven (7) hours would result in credit of seven (7) hours of free service. No credit will exceed one hundred percent (100%) of Customer's Fees for such Service Element for the then-current billing month. A "Service Element" is any element or feature of the Service assigned its own price on ZZ Servers price list or invoice or on any quote given to Customer. All credits referenced in this SLA are 100% Service Credits.

B. Contract Termination Option

Customer may terminate the Agreement, pursuant to Subsection 3(b) of the Agreement, without advanced notice, in the event that ZZ Servers awards it 60 or more days of total credits during any single contract year, provided 3 or more separate instances of Failure occurred during such year. For purposes of this clause, a contract year is the 12-month period beginning on first day ZZ Servers provides Service. Notwithstanding the foregoing, this SLA does not authorize termination of any Service Element for which ZZ Servers purchased telecommunications circuits or other resources for Customer's sole use.

C. Exclusive Remedies & Warranty Disclaimer

The remedies set forth in this SLA are Customer's sole and exclusive remedies for Failure, including without limitation for any breach of warranty, except as specifically set forth in the Agreement.

D. Limitations

This SLA does not cover (without limitation): (a) network performance to Customer's physical location or internet access point (such as a local DSL/cable modem); or (b) failures due to denial of service attacks.

III. HARDWARE REPLACEMENT

60-minute replacement of the following ZZ Servers provided hardware:

  • Hard drive
  • Memory
  • Processor
  • Power supply
  • Network Interface Card
  • Motherboard (results in complete server replacement)
  • Hardware firewall

ZZ Servers will repair or remove and install reasonably comparable replacements if it determines, in its sole discretion, that the hardware is defective. The period listed above begins upon such determination. The period listed above refers only to the time required to physically repair or replace the failed hardware element and does not apply to any time spent: (a) addressing data, operating systems, or other software or systems corrupted or destroyed by hardware failures; or (b) communicating with Customer regarding permissions or instructions.

IV. SUPPORT RESPONSE TIME

  • EMERGENCY tickets - 30 minutes
  • The following are the EMERGENCY categories:
    • Server down
    • Packet loss
    • Routing issue
  • All other tickets - 120 minutes

A tracking number will automatically be provided to Customer promptly after ticket creation, and a human support engineer will review the support request within the timeframe listed above. ZZ Servers may reclassify any ticket misclassified as falling into one of the EMERGENCY categories listed above, and such tickets will not qualify for EMERGENCY treatment. Resolution and repair times vary, and this SLA does not address them.

V. DOMAIN NAME SERVICES

  • Primary DNS availability: 100%

"DNS" means domain name server. A period of DNS failure is any time during which 100% of ZZ Servers Domain Name Servers simultaneously fail to respond to requests for name resolution. This SLA does not guarantee propagation of DNS data across the Internet or the hosting of secondary DNS service for Customer's primary domain in another location, and it does not guarantee against zone inaccuracies due to operator error. No failure listed in the preceding sentence will be considered a Failure.

VI. POWER AVAILABILITY & PERFORMANCE

ZZ Servers will provide power availability sufficient to run Customer hardware 100% of the time. ZZ Servers will also provide the power performance required below.

  • Availability: 100%
  • Voltage fluctuations: +/- 10%

A power Failure is a loss of electrical power or a voltage fluctuation, exceeding the limits above, in any part of the delivery system (utility company supply, on-site generation, UPS, circuit, or power strip) which causes Customer's hardware to shut down. A period of power-related Failure is measured from the time that the support ticket is opened to the time that the electrical supply is restored, and does not include any time required to remedy any issues resulting from the electrical failure.

VII. COOLING & ENVIRONMENT

  • Data Center Temperature: 67 – 74 degrees Fahrenheit
  • Relative Humidity: 35% - 60%

As used in this SLA: (a) relative humidity is the ratio of water vapor density (mass per unit volume) to saturation water vapor density, expressed in a percentage; and (b) both temperature and relative humidity are averages of several measurements, each from one of the Facility's CRAC (computer room air conditioning) units. ZZ Servers will monitor, but is not required to report to Customer on, environmental conditions in the Facility.

Cooling and environment credits apply to fees for Space rental only. Space rental will be considered a Service Element, and if ZZ Servershas not assigned it a specific price, ZZ Servers may determine, at its sole discretion, the portion of fees attributable to Space rental.

VIII. SERVER POWER CYCLING

  • Server power cycling: < 15 minutes

The Service includes an automated system for cycling each individual power circuit. The Customer Portal allows Customer to request an immediate power cycle (a "Reboot Request"). This SLA applies only to requests for power cycling initiated through such automated system. The figure listed above is the maximum period between the time of the Reboot Request and either the actual server power cycling or notice to Customer that the power cycling failed. Any failure of ZZ Servers's system to respond within that timeframe constitutes Failure only if Customer files a trouble ticket requesting a manual server power cycle.

IX. PHYSICAL SECURITY

  • 24 x 365 on-site security

ZZ Servers will ensure the presence of a professional security guard in the building at all times, charged with enforcingsecurity policies. (Those policies require, among other things, that employees, vendors, and visitors wear a badge and that visitors who have not been issued a permanent badge leave a valid U.S. driver's license or passport with the guard while on the premises.)

X. 24 x 365 ON-SITE ENGINEERING

  • 24 x 365 On-Site Engineering,

Support engineers actively on duty on the raised data center floor 24 hours per day, every day of the year.

XI. CREDIT REQUIREMENTS

The following are required for credits:

A. Customer must open a valid and complete trouble ticket through the Customer Portal during any Failure, providing complete information regarding the nature of the problem, including any information reasonably necessary for diagnosis and correction. Customer will provide this notification even if ZZ Servers provides monitoring services.

B. Customer must provide ZZ Servers with accurate and complete designated points of contact, using the Customer Portal. Customer must provide ZZ Servers with accurate passwords for maintenance and repair use by ZZ Servers engineers. Delays or failures caused by Customer's failure to abide by the requirements of this Article XI.B do not constitute Failures.

C. Customer must request any credits by accurately completing the automated SLA Credit Request process online at the Customer Portal within 48 hours of the start of the Failure.

XII. CREDIT LIMITATIONS

A. The minimum period of Failure eligible for a credit is 60 seconds, and shorter periods will not be aggregated. The maximum credit for any single Failure is one month's Service fees. In the event that multiple periods of Failure overlap in time, credits will not be aggregated, and Customer will receive credit only for the longest such period of Failure. The maximum credit during a single calendar year, for all Service Elements combined, is two months' Service fees, regardless of the length of Failure or the number of occurrences. The period of Failure for Network Performance, Domain Name Services, Power Availability & Performance, Cooling & Environment, and Physical Security (Articles II, V-VII, and IX above) begins upon filing of a trouble ticket and ends when the Failure is remedied.

B. In the event that credits for any calendar month exceed 25% of ZZ Servers revenues for such period, ZZ Servers may reduce and pro-rate the value of credits given to all Customers for such period so that the aggregate credit given to all Customers does not exceed 25% of revenues. As used in the previous sentence, "ZZ Servers revenues" and "all Customers" refer to revenues and customers from Internet colocation, and hosting services sold under the "ZZ Servers" brand, and not to revenues or customers from any other business unit operating under another name or providing services other than or in addition to Internet colocation. ZZ Servers may employ such accounting procedures as it chooses in calculating revenues, in its sole discretion, and nothing herein will be construed to require that ZZ Servers disclose non-public information about its finances to Customer or to any party.

C. Credits available pursuant to this SLA apply only to future service delivery. ZZ Servers is not required to provide refunds pursuant to this SLA. If Customer's Signup provides for a Prepayment Period, credit will apply to any renewal of such Prepayment Period, but Customer may instead elect to apply credit to any additional ZZ Servers products or services. If Customer retains a credit balance on termination of the account in question, such credit is forfeited. Notwithstanding the foregoing, credits will not be applied against fees for Professional Services, bundled support, or setup fees.

D. Notwithstanding any provision to the contrary in this SLA, the following do not constitute Failures: (1) downtime during scheduled maintenance or Emergency Maintenance (as defined below) periods; (2) outages caused by acts or omissions of Customer, including its applications, equipment, or facilities, or by any use or user of the Service authorized by Customer; (3) outages caused by hackers, sabotage, viruses, worms, or other third party wrongful actions; (4) DNS issues outside of ZZ Servers's control; (5) outages resulting from Internet anomalies outside of ZZ Servers's control; and (6) outages resulting from fires, explosions, or force majeure. "Emergency Maintenance" refers to any corrective action intended to remedy conditions likely to cause severe Service degradation, as designated by ZZ Servers in its sole discretion. Emergency Maintenance may include but is not limited to actions intended to address hardware or software failures or viruses/worms. As provided in Section 6 of the Agreement, ZZ Servers will exercise reasonable efforts to inform Customer in advance before interrupting the Service for Emergency Maintenance, but such notice is not guaranteed and failure thereof does not constitute Failure.

XIII. Terms of Service / The Agreement

Terms defined in the Agreement will have the same meaning when used in this SLA. In the event of any conflict between this SLA and the Agreement, the Agreement will govern.
