Frequently Asked Questions

No. Our service is pure Pay As You Go (PAYG).

No, you could get started instantly in the trial mode. Supported payment options are PayPal and credit card.

Yes, we have a fully featured RESTful API. The KeyCDN API allows users to manage Zones and receive reports in a straightforward, programmatic way, using conventional HTTP requests. For more information on our API, check the API documentation in the KeyCDN dashboard.

KeyCDN's content delivery architecture has been engineered and developed from square one with simplicity and high performance in mind. Learn more about how KeyCDN is different: CDN Comparison of KeyCDN

Yes, but it has to be legal of course.

KeyCDN calls its CDN instances “Zones”. Each zone has individual settings. 2 different types of zones exist such as Push and Pull. A zone is normally needed for one website. A zone is a URL that you can embed in your website for static websites. A zone has nothing to do with geography. All POPs worldwide are enabled for each zone.

A Pull Zone fetches (pulls) the requested content from your origin server and caches the assets on our edge servers. In most of the cases, a Pull Zone is the preferred option for any content management system (CMS). Don't use a Pull Zone for files larger than 100MB in size or the assets will not be cached.

A Push Zone requires that you upload your content to the CDN storage cloud and distribute it from there to the edge servers. We support FTP(S) or rsync over SSH to upload your data. Push Zones are mainly used for distributing files larger than 10MB or for files that rarely change (such as documents, videos, etc).

It takes just a few minutes. The deployment time is the same for creating or editing a Zone, Zonealias or Zonereferrer.

Yes. Simple, SAN and wildcard certificates are supported. Shared and custom SSL certificates are free of charge. Our certificates are based on SNI.

Yes, you can create the CNAMEs (Zonealiases) you want.

Yes, either through the API or in the dashboard.

Yes, you can purge a single URL either through the API or in the dashboard.

It depends on the type of content and how you build your application. It is possible by using query strings and Cache-control headers for your assets.

If you configure a Push Zone you can upload your content via FTP(S) or rsync over SSH. Pull Zones fetch the content from the origin server.

Yes, you can combine or replace existing CDN implementations such as a Cloudflare Alternative or Akamai CDN.

No, what you use will be deducted from your credits.

The minimum payment is $49, which equals to 49 credits. Please note, unused credits expire after 1 year.

By delivered HTTP-traffic, also HTTP-header data.

Push storage pricing starts at $0.47/GB/month (billed on daily basis). There is no storage cost for Pull Zones.

The configuration of the custom SSL certificate is free of charge. Either issue a certificate yourself (e.g. gogetssl.com or ssls.com) or deploy for free with our Let's Encrypt integration.

The exact downloaded data is charged, not the whole file.

Credits can be loaded to your account and are used to charge for all kind of different services that we offer such as traffic, storage or consulting fees. One credit equals to one USD.

Yes, credits expire after 1 year if there wasn't a payment for more than a year but you can retain them with any payment for another year before the expiry.

Yes, we send a reminder when your balance reaches 0. You are allowed to have a negative balance of 40% from your last payment before we stop content delivery. The second reminder will be send if you reach a negative balance of 20% from your last payment. The third and final reminder informs you that your account has been set to inactive and that content delivery has been suspended. At the latest, you will receive the final reminder after 7 days since the first reminder. Make sure you white-list emails send from @keycdn.com to avoid they end up in your spam folder.

If you’ve enabled auto-payment, you’ll be charged again with the amount that you’ve defined. If auto-payment is disabled, you’ll get several emails when you have a negative balance. If you don’t recharge your account after the third reminder email, your account will be set to inactive and content delivery will stop.

We recommend enabling auto-payment.

The auto-payment will execute when the balance is 0. If the auto-payment fails, your account will stay active and you’ll have time to conduct a payment.

We understand that continuous content delivery is very important. If the auto-payment fails, you’ll get several emails (telling you that you have a negative balance). We don’t block paying customers right away when you ran out of credits. This will give you time to react while content delivery continues for your account.

No, credits are not refundable.

You don’t need to cancel or terminate the account explicitly. If you delete your zones and remove your data on our FTP, you won’t be charged. You can still use your credits later on. If you still want to delete your account, please submit a support ticket.
