General Service Level Agreement

CTC servers guarantees uninterrupted Internet transit (measured on a monthly basis) and continuous power supply, both with a 100% uptime commitment. In case of Internet transit or power interruptions exceeding the 100% minimum for a cumulative period of up to 1 hour within a month of service, the client is eligible for an account credit equivalent to 5% of the Recurring Monthly Fees for the affected services for each additional hour of unavailability, not exceeding 50% of the client's Recurring Monthly Fees unless otherwise specified.

Unless otherwise indicated, all credit calculations will be based on increments of 1 hour of unavailability. This agreement does not cover outages resulting from equipment or events under the control of the client. It also excludes outages due to scheduled or emergency network and facility maintenance, which will be communicated to all customers in advance through our website, not exceeding 180 minutes per month.

Credit issuance will not exceed 50% of the client's Recurring Monthly Fees for the respective month, unless otherwise stated. Additionally, all credit requests must be submitted within 30 days of the incident.

To request a credit via email, please contact sales@ctcservers.com with your account name and the duration of the outage. Your accounts should not have any overdue payments when requesting an SLA credit.

Dedicated Server Hardware SLA

CTC servers guarantees a swift response to hardware issues with a 12-hour hardware replacement SLA for all current dedicated server offerings. The 12-hour countdown starts upon the confirmation of a hardware problem via a ticket response, provided that immediate maintenance is specified. If the hardware isn't replaced within the initial 12-hour timeframe after the issue is detected, you have the option to request a 10% SLA credit. An additional 10% credit can be claimed for every subsequent 12-hour period of delay.

To initiate a credit request, please email the outage details and duration to sales@ctcservers.com. It's important to note that credit requests must be submitted within 30 days of the incident, and the total credit amount cannot exceed 50% of the monthly fee for the affected server.

Ultimate DDoS Mitigation SLA

The Ultimate DDoS Mitigation Service Level Agreement (UDM SLA) offers customers a set of assurances and solutions related to CTC\ servers's performance in delivering DDoS Protection Service, specifically for Layer 3 to Layer 4 (as defined below).

For the purposes of this DDoS Protection Service - DPS Core SLA, the following terms have the specified meanings:

  • Ultimate DDoS Protection (UDM): This refers to the service provided by CTC servers to mitigate the effects of Denial of Service Attacks on customers' Internet connectivity, which is delivered via the CTC servers Backbone.
  • CTC servers Backbone: This is CTC servers's network infrastructure, owned and operated solely at selected points of presence where CTC servers offers DDoS Protection Service (referred to as "Selected POPs").
  • CTC servers Network Operations (CTC servers NOC): This consists of the team at CTC servers responsible for operating, monitoring, and supporting the network infrastructure exclusively within the Selected POPs where CTC servers provides DDoS Protection Service (DDoS Protection).
  • CTC servers Network Security (CTC servers Security): This team is responsible for operating, monitoring, and supporting DPS Core.
  • DDoS Attack (Attack): Denotes a Denial of Service attack on the Internet connectivity provided to customers over the CTC servers Backbone.
  • DDoS Mitigation Event (Event): Refers to the steps taken by CTC servers Network Security, utilizing the Backbone, to reduce the adverse impacts caused by an Attack.

  • Trouble Ticket: This is a customer incident report generated by the CTC servers NOC within its ticketing and tracking systems.
  • Mitigation Request Response Time (Response Time): This specifically measures the time between the opening of a Trouble Ticket by a customer with the CTC servers NOC requesting a DDoS Mitigation Event and the point at which CTC servers NetworkSecurity contacts the customer (or attempts to do so) to commence the necessary troubleshooting and investigation. It does not pertain to the time between the opening of a Trouble Ticket and the implementation of measures required to mitigate an Attack.
  • Event Fee: This consists of fees associated with a specific Event, incurred by the customer.
  • Access Control List (ACL): It denotes a packet filtering method designed to permit or deny network access by IP address or network protocol between a customer's network connection and the CTC servers Backbone.
  • Standard ACL Change Request: This refers to an ACL change request submitted to the CTC servers NOC or CTC servers Security that will be reviewed within one business day, with deployment scheduled upon approval. It may include new ACL(s), modifications to existing ACL(s), and/or removal of ACL(s).
  • Emergency ACL Change Request: This pertains to an ACL change request submitted for immediate review to the CTC servers NOC or CTC servers Security, with deployment scheduled upon approval. Similar to the Standard ACL Change Request, it may include new ACL(s), changes to existing ACL(s), and/or the removal of ACL(s).
  • Included Standard ACL Change Requests: This specifies the number of Standard ACL Change Requests included as part of the monthly subscription.
  • Standard ACL Change Request Rate: This signifies the fee associated with each Standard ACL Change Request.
  • Emergency ACL Change Request Rate: This represents the fee linked to each Emergency ACL Change Request.
  • Emergency ACL Change Request Response Time: This specifically measures the time between the opening of a Trouble Ticket by a customer with the CTC servers NOC, requesting an Emergency ACL Change, and the time when CTC servers Network Security or the CTC servers NOC contacts the customer (or attempts to contact the customer) to initiate the review process for the intended Emergency ACL Change Request. It does not refer to the time between the opening of the Trouble Ticket and the deployment of the ACL change.

Response Time

If a customer suspects they are being targeted by a Denial of Service Attack and wishes to initiate mitigation, there are various methods for them to open a trouble ticket for this purpose. When mitigation requests are made through telephone to the CTC servers NOC (+123 490 189 76) or the Billing Department via a ticket, the CTC servers Network Security Team commits to responding to the customer's request within 60 minutes. In cases where this Response Time commitment is not met, CTC servers will provide the customer with a credit amounting to 50% of the Event Fee paid by the customer, or 50% of the Event Fee that would have been paid by the customer, should the mitigation fall within the "Included Mitigation Days."

ACL Change Request Response Time

When a customer wishes to make a standard, non-emergency adjustment, change, or removal to an Access Control List (ACL), they have several methods at their disposal to create a trouble ticket for a Standard ACL Change Request. If Standard ACL Change Requests are submitted via telephone (+123 490 189 76) to the CTC servers NOC or CTC servers Network Security or through the Customer Portal, the CTC servers Network Security Team commits to responding to the customer and commencing a review of the ACL request within one business day of the request submission. If CTC servers fails to meet this Standard ACL Change Response Time commitment, the customer will receive a credit equivalent to 50% of the Standard ACL Change Request Rate paid by the customer, or 50% of the Standard ACL Change Request Rate that would have been paid by the customer, in cases where the obligation for Standard ACL Change Request Response Time is not fulfilled.

Exceptions

The DDoS Protection SLA does not entitle the customer to credits in the following circumstances associated with or caused by the CTC servers Backbone:

  • Events beyond CTC servers's reasonable control, including governmental actions, war, insurrection, sabotage, embargo, fire, flood, strikes, or other labor disturbances, transportation interruptions or delays, unavailability or interruptions in telecommunications or third-party services, failures of third-party software, or inability to obtain necessary raw materials, supplies, power, or equipment required for providing the DDoS Protection Service.

Network/Global IP Transit SLA

CTC servers is dedicated to maintaining its network to ensure the highest possible Internet performance for all customers. To fulfill this commitment, CTC servers offers the following guarantees to all on-site Internet clients:

  • A 100% guarantee of uninterrupted Internet access.
  • Packet loss will not exceed 0.1% within an average 30-day period (applicable to Level 3/PCCW Carriers Only).
  • The average jitter on CTC servers's backbone network will be 285ms or less.
  • The maximum jitter on CTC servers's backbone network will not exceed 10ms for more than 0.1% of a calendar month.

The CTC servers Network Security Team commits to responding to the customer's request within 60 minutes.

In addition to the above performance guarantees, CTC servers will, for all premium network clients, take every possible measure to ensure that all client traffic reaches its destination in a timely manner, similar to and in line with the performance of any other carrier in the region. These measures include optimizing routing tables to direct traffic to the Internet through the best available upstream link. CTC servers also guarantees that efforts will be made to minimize any negative impact on users due to DDoS attacks from other customers on our network. Null routing of an IP address is considered a last resort on our network, with filtering being the initial approach. Downtimes related to null-routing of an IP or billing issues are not counted against the SLA.

Credit Requests and Payment Procedures

To claim a credit under the Network/Global IP Transit SLA, the process is as follows: Open a ticket and request a credit from our Billing Department.
