Simple setup: point a zone at what you already run. We are a delivery layer, not a processing layer: we do not transcode, re-package or host your LMS, and that is exactly why nothing we do can break your course platform.
- Works with what you have: any HTTP origin, S3, Swift, Rsync, Wasabi or our Cloud Storage, plus media servers such as Wowza, NGINX RTMP and FFmpeg for live classes.
- Test before you switch: run it on a temporary hostname against one course, then change the URL in your platform when the numbers look right.

Questions buyers ask about a CDN for online education
BlazingCDN delivers lecture recordings, live classes and course files from the edge, so a whole cohort can press play in the same minute. Pricing runs from $5 per TB down to $2.50 per TB with no capacity to commit, and 100 TB of course delivery costs $415 a month (as of October 2026).
What does an e-learning CDN cost at 100 TB in term time?
BlazingCDN charges $415 for a 100 TB month of course delivery and $92.50 for a 20 TB month (as of October 2026), with no capacity reserved in between. Billing follows the terabytes actually delivered, so a quiet summer costs less without renegotiating anything. For example, a platform running two 100 TB term months and one 20 TB holiday month pays $415 in each term month and $92.50 in the holiday month.
The tiers step down from $5 per TB for the first 5 TB to $4.00 per TB between 25 TB and 100 TB. The rate is the same for students in the US, Europe and Asia, with no request fees and no regional multipliers. No long-term contract applies, and billing is pay as you go or monthly. The $25 monthly minimum covers the first 5 TB, which suits a small course catalogue between intakes.
How does BlazingCDN handle thousands of students starting one lecture?
BlazingCDN absorbs a 9 a.m. lecture start by caching each video segment once per region and serving every later request from the edge. Origin shield adds one upstream layer, so the origin sees a single fetch per segment instead of one per student. The network-wide average cache hit ratio is 96% or higher.
The player chooses among the renditions in one manifest, for example six bitrates, so students on weak mobile connections still get a playable stream. Anycast routing sends each student to a nearby node and fails over automatically when a node drops. Latency measured June 2026 on a 100 MB HTTPS download was 27 ms in Europe, 24 ms in North America and 47 ms in Asia. A cohort of 3,000 students watching a 1 GB recording moves 3 TB, which stays inside the first tier and is billed at the $25 monthly minimum (as of October 2026).
Does BlazingCDN host my LMS or transcode course videos?
BlazingCDN does neither, because BlazingCDN is a delivery layer: no LMS hosting, no transcoding and no re-packaging of streams. The LMS, the encoder and the course catalogue stay on your platform. BlazingCDN caches and serves the finished files and segments, which is why a CDN change cannot break course logic.
The platform connects to what a school already runs. Origins can be any HTTP server, S3, Swift, Rsync, Wasabi or BlazingCDN Cloud Storage at $0.015 per GB per month (as of October 2026). Live classes can come from media servers such as Wowza, NGINX RTMP and FFmpeg, delivered through the HLS Streaming CDN. Interactive features that rely on WebSockets, such as live chat or shared whiteboards, need a separate service, because BlazingCDN does not offer WebSockets. Edge compute and HTTP/3 are also not offered, so course logic stays on your own servers.
Can a university test a CDN on one course first?
BlazingCDN offers a 14-day testing period on real production traffic, and the test can start with one course or one intake. The course runs on a temporary hostname first, then the URL in the platform changes once the numbers look right. The current CDN keeps running throughout, so students see no cutover.
Onboarding takes about one hour with an engineer, and a KYC check is completed before production traffic. A wider move can use a weighted DNS split, sending part of the traffic to BlazingCDN as a second CDN. For example, routing one intake of 2,000 students through BlazingCDN might produce 5 TB in a month, billed at $25 (as of October 2026). Real-time statistics and Prometheus metrics show cache hit ratio and throughput during the test. The 24/7 helpdesk routes questions to an engineer, who replies within 3 business hours.
How do signed links stop paid course videos being shared?
BlazingCDN signed links carry an HMAC signature with an expiry time, so a shared lecture URL stops working once the window closes. A link can also be bound to one IP address, or limited to a set number of IPs per URL, which defeats posting a course link in a public forum.
Additional checks sit on top. Referrer and user-agent rules block embedding on unknown sites. Cookie checks, standard and extended, tie playback to a logged-in session. Geo allow and block lists enforce licensing by country. HTTPS is enforced, insecure requests are refused, and courses can run on your own hostname and SSL certificate. A Googlebot bypass keeps the public catalogue indexable while paid lessons stay locked. All of these controls are included in the per-TB rate, from $5 down to $2.50 per TB (as of October 2026).
