Frequently Asked Questions

About CDN


What is to question is a high performance, LSCache enabled CDN service created by LiteSpeed Technologies. It is currently in beta and is available worldwide free of charge (up to a limit).

What CMS's can I use with to question

Currently, the only CMS you can use with is WordPress. Your WordPress installation must be able to use the LiteSpeed Cache for WordPress plugin.

How many GB can I use on to question provides free bandwidth quota that resets every month. The amount of free bandwidth you receive depends on your origin server. Please check our quota page for the available options. If you feel that your domain is in an incorrect tier, please try to refresh the domain key in LSCWP. If that does not update the server type, submit a ticket or contact us on Slack.

Do I need to register on to use the online services?Link to question

No, you can use the services as an anonymous user. However, if you do register for, you will receive benefits, such as:

  1. The ability to check the online service’s status, as well as any error message related to it.
  2. The opportunity to receive extra promotional credits once you achieve a certain level of usage.
  3. Extra convenience, in regards to troubleshooting, with the LiteSpeed team.

What happens if I use more than the allotted data?Link to question

If you use over 20GB in a month the DNS will change automatically so visitors will be directed to your origin servers again.

How does using speed up my site?Link to question reduces the physical distance requests must go to deliver your site to its visitors by setting servers up across the world. Unlike other CDN services though, has the capability to cache dynamic content, meaning more content can be cached for more of your users. With less physical distance and more caching opportunities available, can deliver sites faster than any other service ever has.

What web servers are compatible with to question

All web servers, including Apache, Nginx, OpenLiteSpeed, etc, are compatible with acts as a CDN only and will not take the place of any web server.

Does offer any Anti-DDoS features?Link to question

If you enable our RECAPTCHA protection inside of the panel for the domain, we will detect if there is a high influx of connections going to your domain. If there is, we will have them verify via RECAPTCHA, which should help protect against Layer 7 attacks. We also have many security related features working behind the scenes to protect against DDoS attacks, such as blocking known bad IPs and preventing WordPress brute force attacks.

How many websites can each account support?Link to question

There is currently no limit to how many domains can be connected to each account.

I ordered credits, but they did not appear on my account.Link to question

Check your ‘order is complete’ email for a link within the email to view the status of your credits. Click that and screenshot it. Send us a ticket at with the screenshot and we will look into it.

Why should I post on social media that my site uses to question

Because we are growing still, we require word of mouth from users like you to grow the community. As a token of our gratitude, we will provide anyone who mentions on Twitter that they use as their backend, with bonus domain level credits. These credits can be utilized the same as all other domain level credits. At the moment, there is no set amount of credits you will receive (there is a minimum though); we will give as many as we decide the post is worth.

Are there substantial performance improvements planned in addition to increasing the POP locations?Link to question

We consistently update with new features and performance improvements. Make sure to stay alert for all the cutting edge changes!

How do I get started using to question

To get started, just follow our onboarding document, and if you have any questions you can reach us on Slack and/or Twitter.

What’s the difference between QUIC and HTTP/3?Link to question

QUIC was originally a Google effort to improve HTTP/2 by transporting it encrypted over UDP (as opposed to TCP). In 2016, the Internet Engineering Task Force (IETF) began working to standardize the protocol. Part of that process involved splitting QUIC into the transport and application protocols. For some time, the application protocol was referred to as HTTP-over-QUIC, but in November of 2018, the IETF announced that HTTP-over-QUIC would be called HTTP/3.

About Beta

Is considered production ready?Link to question

Currently, is still in beta. There is currently no ETA on when it will be out of beta.

How much will cost after it’s no longer in a beta state?Link to question

No decisions have been finalized in regards to the future cost of We have decided we will continue offering a free tier, so everyone gets a chance to try it, and those who use LiteSpeed Web Server will get a larger quota for the free tier.

How does know the correct IP address of the server where my site is located?Link to question

The LSCache plugin will auto update to recognize the correct IP address based on the WordPress installation, but it can also be manually updated through the domain overview on the panel inside

Will a site using test yes for QUIC on to question

Yes. When testing, please make sure your website is set up properly and points to

How do I check my DNS settings?Link to question

There are multiple tools to check DNS settings. Note that if you see a CNAME result, check to make sure that it matches your expected target.

  1. The simplest way to check your DNS setting is to ping your domain. Ping your domain from the Windows command line or Linux SSH terminal.
    To see if your domain is on the network, check that the IP address matches a IP or compare it to the ping results for the CNAME record assigned to your domain (e.g.
  2. Use the online DNS checker tool. If you see different IPs listed globally, that means the site is on our CDN network.
  3. Use the MX toolbox. If you see different IPs listed globally, that means the site is on our CDN network.

What is QUIC Backend?Link to question

QUIC Backend is a new feature that enables to use QUIC to connect to backend servers. The backend server must have QUIC enabled and available for access (some hosts block the port). Make sure that QUIC is available on the backend because if it is not available this option may slow the performance of your site rather than improve it.


How do I use my root domain (such as for to question

If you want to use your root domain you have to use a DNS provider which supports CNAME flattening or “ANAME”.

Check out our DNS guides in our Onboarding document to more information.

Do I have to use a root domain for the CNAME record?Link to question

It is not required to use the root domain, subdomains can be used as well.

With other CDN providers, I can usually use a subdomain, such as, so why do I need to point the entire domain to to question

Because it isn’t just using a subdomain for static content, functions as a reverse proxy in front of the entire site, it isn’t just using a subdomain for static content. So the site itself has to point to the CDN. With other CDNs, the most they can reliably cache are your assets (even that is somewhat untrue – static files just change very infrequently). In other words, when using another CDN, browsers will always visit your server first. The secondary requests are handled by the CDN. With, we can cache your whole site on our CDN network, enabling you to serve everything from cache in a locale advantaged manner.

What does verification of the CNAME do?Link to question

CNAME verification tests to make sure your DNS configurations are set up correctly. It will toggle the DNS to point your site to POPs and run a test to see if your site is pointing to the POPs. If that succeeds it will generate a certificate if auto SSL is enabled. Once that is complete your site is verified and running on At any point if there is a failure, the DNS will revert back to your origin server.

Is CNAME verification required?Link to question

Yes, without CNAME verification your site will not function properly.

How can I tell if the CNAME is properly set up?Link to question

If CNAME verification is completed successfully, your CNAME is most likely set up properly. To better verify you can visit your site in a private browser.

Another way to verify that your CNAME records are set up correctly is to ping your domain (ensure it’s the default one you use to access your website www/non-www) and the CNAME record has provided you. The IPs should match. You can also check to see if there is a x-Qc-pop response header; this will only show if the CNAME setup is working properly.

SSL Certificate

Can I generate the SSL Certificate if I skip the CNAME?Link to question

No, you cannot generate an SSL Certificate via if you do not set up the CNAME properly.

Approximately how long will it take to generate an SSL Certificate?Link to question

It normally takes up to a minute to generate an SSL Certificate. If it does not generate for you, please contact us.

If I already have an SSL certificate on my site, do I need to do anything in the panel for SSL to work?Link to question

If you have your own certificate that you want to manage yourself, you can do so by adding the cert, key, and certificate chain on the dashboard. Do note that you will need to re-upload the certificate every time you update the certificate in order to keep it up to date.

Alternatively, you can use the Generate and Auto SSL settings on the dashboard. We will manage the expiration update automatically.

We highly recommend that you keep your certificate up to date on your origin server in order to properly maintain the connection with


What does cache?Link to question caches both static and dynamic content. To cache static content though, the “Enable Static Cache” option must be set to “YES”.

Can I bypass the CDN?Link to question

Yes, you can easily bypass the CDN. In your dashboard, navigate to the domain you want to bypass, click on the ‘CDN’ tab, then go to CDN Config in the left hand menu. On the following page toggle Bypass CDN to ON.

Can I purge the CDN’s cache?Link to question

Yes, you can purge the cache by clicking the “Purge All CDN Cache” button in the Domain Overview section of the dashboard. The normal LSCWP purges will purge the QC cache as well.


Can I use the crawler function inside of the LSCache for WordPress plugin with to question

Yes, the crawler function does work with The crawler function will crawl the POP closest to the origin server. If you have a LiteSpeed backend server it will also be populated by the crawler.

Does the crawler automagically detect and warm up the cache on the CDN POPs?Link to question

If the LSCache for WordPress plugin has the `Crawler -> Site IP` setting filled, the crawler will bypass the CDN and go directly to the server tied to `Site IP` when it runs, meaning if it is not pointed to it will bypass caching on it. If that setting is empty, the crawler function will crawl the POP closest to the origin server. If you have a LiteSpeed backend server, it will also be populated by the crawler. In the future, we will have a crawler function available to crawl more POPs.


I believe I should have received the activation email already, but I haven’t; why not?Link to question

Please check your spam folder to make sure it was not sent there. If it is not there either, please contact us for further assistance.

Why can't I generate an SSL Certificate?Link to question uses Let’s Encrypt to generate SSL Certificates. If it fails to generate the certificate, it may be due to the DNS. Please wait a few minutes and try again. If it still does not work, let us know and we’ll assist you.

I set the CNAME up, so why is showing an error for the CNAME setup?Link to question

Different DNS providers can take different lengths of time to propagate the records, taking anywhere up to 48 hours.

Why is my site not showing that it is pointed to Or why is my site throwing 404 errors?Link to question

You may have your CNAME pointing to the wrong domain, meaning your site is not set up correctly. For example, if your site is configured to use, you should be updating the CNAME record for www. If instead your site is configured to use, you should be updating the CNAME record for the root domain. Updating the incorrect CNAME record could result in redirecting to the correct domain which is not behind or finding a domain that doesn’t exist on your server.

Why is my website indicating that it is not using QUIC even though it should be?Link to question

The two most likely possibilities are you do not have an SSL Certificate, or your DNS is not pointing to

How do I tell if my site is caching on to question

You can check the x-Qc hit/miss response header. If it shows ’hit’, it is caching.

Why isn’t there a x-qc hit/miss response header for static files like CSS, JavaScript, image, etc?Link to question

Make sure that the “Enable Static Cache” option is set to “YES”. Also, the static file cache depends on the ‘Expires’ or ‘Cache-Control’ response header from the backend server. Please make sure that at least one of these is present.

Why hasn’t my PageSpeed score increased, but my site loading speed has? Or vice versa?Link to question

The pagespeed score has no relation to the actual loading time. Pagespeed is a relative score based on how good you are at doing best practices (which doesn’t always mean fastest.)

Why am I getting a 503 error with to question

If you are receiving a 503 error when visiting a site that is pointed to, there is an issue with serving the website. Please contact us so we can diagnose the issue.

Why am I getting a 520 error with to question

520 Origin Server Unavailable: The connection to the origin server could not be completed.

The 520 error indicates that the POP was unable to connect to the origin server. Most likely, the issue is a firewall at the origin server blocking connections. This is problematic because acts as a proxy service for your domain; it requires access for uncached requests. Try adding the IPs to the firewall or request that your hosting provider do so. These IPs change often, though, as new nodes are added and removed. Note that the IP list provided is not necessarily nodes that browsers will visit. This is the list of nodes that will contact your server.

The IPs are automatically updated for hosts that use the Imunify360 and BitNinja security systems. If you or your host use a different security system that can pull from an IP list, please let us know and we’ll contact them!

If your server is not using any server-level firewall, or the IP’s have been added already, next, check if any application level firewall is in use (such as Wordfence for WordPress). It should include a similar allowlist function.

Why am I getting a 521 error with to question

521 Origin Server Timeout: The connection to the origin server timed out.

The 521 error indicates that the connection between the POP and your origin server timed out. ‘Timing Out’ means that there was no activity for a lengthy period of time, so the connection is assumed to be dead.

Why am I getting a 524 error with `524 Site Not Found: The site is not registered with!`Link to question

The 524 error indicates that the domain that is visiting the node is not registered as a domain on If this is incorrect, please contact us.

My website isn't using QUIC, what should I do?Link to question

If you have verified your domain from inside the CDN’s Domain Management Panel, it is most likely that the DNS has not yet propagated. Wait a while and check again. If it’s still not working, check if your browser has QUIC support. If you’re unable to verify your domain, ensure that your DNS records are set correctly.

How do I handle an Invalid Error Certificate?Link to question

If you see an Invalid Certificate issue, go to the Domain Management page, and click Generate Certificate to set your certificate. If you are using your own SSL, please ensure that it is valid.
