Who do I contact with questions about my monthly invoice?
Cogent has a monthly-based bill cycle that is processed after the 20th of the month. We bill a month in advance, so a bill for the January 20th cycle reflects your payment due for service from February 1 - February 28th. For the first month that you receive service, you will have an invoice that reflects the prorated amount back to your installation date, PLUS the amount for the next month.

What is Cogent's SLA?
Cogent offers one of the best SLAs in the industry. Cogent's SLAs are listed under each product description and can be viewed by visiting the appropriate product page(s) in which you are interested.

How do I request an SLA credit?
In order to initiate a claim for Service Credit, a customer must contact Cogent's
customer service group within seven (7) business days after the end of the month for which credit is requested. The Service Credit request must provide: (a) the customer name and contact information; (b) the date and beginning/end time of the claimed outage or failed metric or the ticket number; and (c) a brief description of the characteristics of the claimed outage or failed metric. The customer will be notified via e-mail upon resolution of the request. If approved, Cogent will issue a Service Credit to the customer's account, appearing on the next invoice issued. Service Credits will be credited against a customer's monthly payment for Monthly Recurring Charges and may not be received in the form of a refund.

Can I call a Cogent technician for help in configuring my LAN and/or servers?
Cogent technicians typically do
not provide support beyond the customer demarcation (i.e. customer LAN). If you need assistance, however,
email us and we'll help troubleshoot your issue.

Are there consultants that Cogent recommends to help me with my service?
Yes. Several of our customers have requested assistance in setting up their networks and monitoring their service, so we have pre-qualified several Systems Integrators. Please contact our
support group for more information.
