FILES ON DEMAND · LARGE DOWNLOADS
Files on Demand CDN
Import your catalogue once and the CDN holds the copies: documents, archives, installers and media served from the closest node without your origin staying in the delivery path.
From $5/TB down to $2.50/TB, so 100 TB of downloads is about $415 a month · 14-day testing period on real traffic · $25 monthly minimum waived · Engineer reply within 3 business hours

What 100 TB of downloads costs
Progressive tiers work like tax brackets: each rate applies only to the traffic inside its range. Requests, HTTPS, custom domains and origin shield are included, and the rate is the same in Europe, Asia and America.
TIER 01
First 5 TB
$5.00 per TB
- $25 for the whole tier
- This is also the monthly minimum
TIER 02
5 to 25 TB
$4.50 per TB
- $90 for the next 20 TB
- 25 TB in total: about $115
TIER 03
25 to 100 TB
$4.00 per TB
- $300 for the next 75 TB
- 100 TB in total: about $415
100 TB a month works out at $415
Each tier is billed only on the traffic inside it, so the tiers add up rather than replace each other. 25 TB is about $115, 500 TB is about $1,815, and above 500 TB a month we quote it for you.
Four catalogues that belong in the CDN
Files on Demand is for libraries that are served far more often than they change, and that you would rather not keep a server online for.
Software and installer catalogues
Installers, patches, disk images and asset packs up to 50 GB per file. Import once and every release stays available without your build server answering a single download.
Document and archive libraries
PDFs, manuals, price lists, ZIP and ISO archives. Catalogues that are read constantly and updated occasionally, where the CDN holding the copy is cheaper than keeping storage online for it.
Media assets that are not video
Audio files, high-resolution images, design sources and fonts. Everything a media team ships that is not a video stream, on the same zone and the same tiers.
Partner and press deliveries
Full-quality masters and press kits handed to partners on a signed link. Large, infrequent, and never worth exposing your origin for.
AdTech and MarTech
Banner creatives, HTML5 ad units, VAST documents, tag scripts, tracking pixels. Small files where tens of milliseconds decide whether the ad renders.
Education, docs and IoT
Course PDFs and slides, short lesson clips, subtitle files, map tiles, firmware and OTA updates for devices in the field.
Anycast CDN or Files on Demand?
Both deliver the same file from the same network. The difference is where the file actually lives, and whether your origin has to stay online.
Anycast CDN pulls and caches
- Your origin is the source of truth
- Files are fetched on the first miss
- Origin must stay online and reachable
- Best when content changes often
Files on Demand imports and holds
- The CDN keeps the copies
- Lazy import pulls a missing file from a proxy URL
- Origin can go quiet after the import
- Best for catalogues read far more than written
Which one you want
- Changing constantly? Anycast CDN
- Served for years? Files on Demand
- Video library? Video CDN
- Not sure? Ask an engineer, it takes one call
How a file gets into the CDN
Give the origin link once and the import runs. Anything missing on the first request is fetched from a proxy URL you nominate, so the catalogue fills itself instead of waiting on a migration script.
First byte without the wait
Files are served from the node closest to the user, so a download starts immediately instead of queueing behind your origin. Range requests keep multi-gigabyte files resumable.
Advanced access controls
Limit access by IP address range, by geography, or through signed URLs with an expiry, so a link works only for whoever it was issued to.
Any file type
Documents (PDF, DOC, XLS), archives (ZIP, RAR, ISO), media (MP3, MP4, JPG, PNG) and executables (EXE, BIN, DMG). Up to 50 GB per file, with no size surcharge.
Security and flexibility
Hotlink protection, geo-blocking and IP filtering keep files away from anyone the link was not issued for. Flexible import settings and custom HTTP headers control how content is served.
An engineer, not a ticket queue
Send your catalogue size and current storage, and our team sets the import up with you. An engineer replies within 3 business hours.
Controlling who gets the file
- Content Protection
- Token Authentication
- Referrer Checks
- Smart Caching
- Country and Region Blocks
Replication and import
- Replicated across Europe, Asia and America: the same file is held in more than one region, so a node or a region going quiet does not take your catalogue with it.
- Lazy import: if a file is not yet in CDN storage, it is fetched automatically from a proxy URL you nominate, so the catalogue fills as it is used.
- Speed and traffic management: set speed limits per resource or leave bandwidth unrestricted, depending on what the catalogue is for.
- Statistics and monitoring: track delivery and performance per resource through the API or the panel.
Full control over file access and security
BlazingCDN’s FOD CDN offers robust security features to protect your files, giving you complete control over how and when your content is accessed:
- Advanced Access Controls: Limit access by IP address ranges, geographic regions, or through URL signatures to keep unauthorized users out.
- Flexible Referrer Policies: Control which domains can access your files by configuring custom referrer headers, preventing unauthorized hotlinking.
- Country-Based Restrictions: Block access from specific countries to comply with legal regulations or protect your content from unauthorized regions.

The rest of the product line
Anycast CDN
Classic pull cache for player scripts, posters, thumbnails and subtitle files. Files up to 50 GB, on the same progressive tiers.
Video CDN
Your catalogue is replicated inside the CDN and served from the closest server, so the origin can leave the delivery path entirely.
HLS Streaming CDN
Delivery for streams you have already encoded: HLS, LL-HLS and DASH, with manifests and segments cached on separate rules.
