Roblox does not currently appear to use Cloudflare as the primary CDN, reverse proxy, or authoritative DNS provider for its core public domains. Current DNS, hostname, and routing evidence instead points to Roblox-operated edge and delivery infrastructure, supported by selected cloud services such as AWS. That does not prove Roblox never uses Cloudflare for a limited, private, or undisclosed service.
What “uses Cloudflare” can mean
Cloudflare is not a single hosting service. A company can use it for authoritative DNS, CDN delivery, reverse-proxying, web application firewall (WAF) protection, DDoS mitigation, bot management, or developer products such as Workers and Tunnel.
Cloudflare can also appear on the player’s side. Someone may use Cloudflare’s 1.1.1.1 DNS resolver or WARP, but that says nothing by itself about which company hosts Roblox.

Under a normal Cloudflare setup, a domain commonly delegates authoritative DNS to Cloudflare nameservers and proxied web records resolve through Cloudflare-controlled edge addresses. Cloudflare explains this model in its DNS documentation.
Current public observations for Roblox’s core domains show a different pattern:
roblox.comuses nameservers from NS1 and Roblox’srbxinfra.netinfrastructure, rather than Cloudflare nameservers.www.roblox.comresolves through Roblox-controlled hostnames includingtitanium.roblox.comandedge-term4.roblox.com.- The observed address for
www.roblox.comwas associated with AS22697 – ROBLOX-PRODUCTION, not a Cloudflare network address.
These records are documented in Cloudflare Radar’s roblox.com data and its www.roblox.com data. Cloudflare Radar is a measurement and domain-information service; a domain appearing there does not mean that the domain is a Cloudflare customer.
Does Roblox use Cloudflare DNS?
Not for the primary roblox.com zone, based on the observed nameservers. Cloudflare Radar lists:
dns1.p06.nsone.net
dns2.p06.nsone.net
dns3.p06.nsone.net
dns4.p06.nsone.net
ns01.rbxinfra.net
ns02.rbxinfra.net
ns03.rbxinfra.net
ns04.rbxinfra.netThis is materially different from a standard Cloudflare-authoritative configuration using *.ns.cloudflare.com nameservers. It indicates that Roblox’s main domain DNS is managed through NS1 and Roblox infrastructure, not Cloudflare’s normal authoritative DNS service.

Does Roblox use Cloudflare as a CDN?
The public evidence points instead to Roblox’s own delivery infrastructure for its principal domains. Roblox’s content-delivery domain, rbxcdn.com, uses Roblox-controlled nameservers, and public certificate information identifies Roblox Corporation. See Cloudflare Radar’s rbxcdn.com record.
That is consistent with Roblox operating its own asset-delivery network. It does not prove that every asset, regional service, or third-party integration uses exactly the same network. DNS results can vary by hostname, geography, resolver, IP version, and time.
What infrastructure does Roblox use instead?
Roblox describes a largely self-operated, hybrid infrastructure model rather than a platform hosted entirely by one public-cloud or CDN provider.
In its infrastructure disclosures, Roblox says it operates data centers, manages its own hardware, compute, storage, and networking, and connects facilities through a dedicated backbone. Its 2023 infrastructure article describes a custom hybrid private cloud that runs primarily on premises. Roblox’s 2025 Form 10-K also describes owned and operated data centers, private backbone connectivity, and direct interconnections with internet providers.
Roblox does use Amazon Web Services for selected workloads, including some databases, object storage, message queues, and additional capacity during demand spikes. The accurate description is therefore:

- Not: “Cloudflare runs Roblox.”
- Not: “Roblox uses no cloud vendors.”
- More accurate: Roblox primarily operates its own infrastructure while supplementing it with selected public-cloud services.

Does Roblox use Cloudflare for DDoS protection or its WAF?
Roblox clearly operates substantial internal security and traffic-protection systems. In a 2025 security article, Roblox described an ML-powered workflow that analyzes Roblox-specific traffic, filters noise, detects attacks and malformed requests, and generates service-specific WAF allowlists. That is evidence of an internally developed security capability.
However, it does not establish that every Roblox security function is proprietary or that Roblox never supplements its systems with a third-party provider. Public material reviewed here does not confirm a complete vendor inventory. The careful conclusion is that Roblox’s public security architecture is visibly substantial and internally operated, while limited Cloudflare use cannot be ruled out.
See Roblox’s security organization overview for its description of the WAF workflow.
What about Roblox game traffic?
Website traffic, CDN assets, API calls, and live game-session traffic are separate categories. Roblox’s infrastructure disclosures describe Roblox-operated servers, regional data centers, and backbone networking, which supports the conclusion that gameplay is not simply delivered through Cloudflare’s ordinary web CDN.

Still, public DNS for roblox.com cannot identify every connection made by the Roblox client. A session may involve different hostnames, regional services, creator content, voice or moderation systems, and third-party integrations. It would be too broad to claim that every packet in every Roblox session bypasses Cloudflare.
Why might you see Cloudflare while using Roblox?
You use 1.1.1.1 DNS
If your device or router uses Cloudflare’s 1.1.1.1 resolver, Cloudflare is answering your DNS queries. Roblox can still use its own authoritative DNS and hosting infrastructure.
You use WARP
Cloudflare WARP routes your device’s traffic through Cloudflare’s network. That makes Cloudflare part of your connection path, not necessarily part of Roblox’s server-side infrastructure.
Your school, workplace, ISP, or security software uses Cloudflare
Network administrators may use Cloudflare Gateway or related filtering services. A browser or security product can also label traffic by resolver, transit provider, or inspection layer rather than by the origin hosting Roblox.
The site is Roblox-related but not Roblox
A creator’s website, game-development tool, proxy, API, image host, analytics endpoint, or unofficial Roblox service may use Cloudflare even if Roblox itself does not.

You saw a Cloudflare error page
A Cloudflare-branded challenge or error page does not automatically prove that Roblox’s origin is hosted behind Cloudflare. Check the exact hostname shown on the page. The response may come from a local proxy, network filter, third-party site, or an intermediary service.
How to troubleshoot a Cloudflare error when opening Roblox
- Read the error page and identify the exact hostname.
- Check whether Cloudflare WARP,
1.1.1.1, a school or workplace network, VPN, browser extension, or security filter is active. - Try the same Roblox page on mobile data or another trusted network.
- Compare DNS-only mode with WARP traffic routing if you use Cloudflare’s app.
- Test whether the problem affects
www.roblox.com, the Roblox launcher, or only an unrelated third-party Roblox site. - Consider that the page may have been generated by your ISP, browser security layer, or local proxy rather than Roblox.
Changing DNS can sometimes fix a lookup or routing problem, but it does not change Roblox’s hosting provider. It only changes how your device finds a domain.
What the evidence can—and cannot—prove
The strongest evidence is a direct Roblox statement naming a vendor, followed by a vendor case study or customer disclosure. DNS nameservers, CNAME chains, IP ownership, autonomous-system data, certificates, headers, and challenge fingerprints are useful supporting evidence, but none provides a complete view of private contracts or internal services.

Roblox could still use Cloudflare for a limited subdomain, private service, temporary migration, or third-party property without changing the main domain’s nameservers.
Verdict
Based on current public DNS, routing, and Roblox infrastructure disclosures, Roblox probably does not use Cloudflare as the primary CDN, reverse proxy, or authoritative DNS provider for its core public infrastructure. Roblox appears to operate its own edge, content-delivery, data-center, and backbone systems, with AWS used selectively for particular workloads and capacity.
The answer is not an absolute “never.” Public DNS cannot rule out undisclosed or limited Cloudflare usage, and seeing Cloudflare on your own connection usually reflects your DNS resolver, WARP, network filtering, or a Roblox-adjacent website—not proof that Roblox itself is hosted on Cloudflare.
