FAQ
gocdn FAQ: how to pay, upgrading plans, node limits and free trials.
Frequently asked questions
Which billing periods are supported, and can I change at renewal?
You can choose monthly, quarterly, semiannual or yearly, and the period can be changed at renewal. Longer periods cost less per month.
What is gocdn?
gocdn is a private-deployment CDN solution. You deploy nodes on your own servers and manage caching and acceleration, HTTPS certificates, CC protection, WAF and real-time monitoring from one controller, with a complete HTTP API.
Does visitor data pass through gocdn?
Visitor traffic does not. The controller and nodes run on your servers, and access logs and site content stay on your own machines. The controller only reports running status, usage totals, and suspicious IPs and request samples used for threat intelligence.
Is a trial available?
Self-service trials are not available at present. Please contact us to arrange one.
Which operating systems are supported?
Controller: Debian 13 / Ubuntu 26.04 or later. Nodes: Debian 12/13 or Ubuntu 24.04 LTS or later. All 64-bit Linux.
Which payment methods are supported?
Bank transfer, credit card and PayPal are accepted, and invoices are available on request. The license is activated once payment clears, usually within one business day.
How do I upgrade my plan?
You can upgrade at any time and pay only the prorated difference for the remaining term. New limits and features apply right away, with no reinstall.
What happens if I exceed my node limit?
Existing nodes keep serving traffic; you cannot add more. Upgrade to a higher plan, or contact us for extra node capacity.
Do prices include server costs?
No. Prices cover the gocdn software license. Customers provide their own Linux servers for nodes and the controller, from any cloud provider or your own data center.
Security FAQ
How are legitimate visitors protected from false blocks?
New rules only log, without blocking, for their first 3 days. A false positive can be excepted in one click from Attack Logs, for that site and that rule only.
How do the basic rules differ from Rules Update?
Basic rules come with each release upgrade. With Rules Update, CRS converted rules, vulnerability patches, emergency rules and the high-risk IP library sync hourly, with no version upgrade needed.
How soon after disclosure is a new vulnerability covered?
Controllers with Rules Update sync every hour; others get coverage with the next release.
Is DDoS protection supported?
Application-layer (CC) attacks are covered. High-volume network-layer attacks depend on the protection capability of your data center and network.
