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

Anycast CDN or Files on Demand?
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
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.

Questions buyers ask about the Files on Demand CDN
The BlazingCDN Files on Demand CDN imports and holds installers, archives, documents and media files up to 50 GB each, so the origin can leave the delivery path. Pricing runs from $5 per TB down to $2.50 per TB, and 100 TB of downloads costs $415 a month (as of October 2026).
How much does delivering 1,000 TB of installer downloads cost?
BlazingCDN charges $3,315 for 1,000 TB of downloads in a month (as of October 2026), billed on progressive tiers. The first 5 TB costs $5 per TB, the next tiers step down through $4.50, $4.00, $3.50 and $3.00 per TB, and each terabyte is billed at the tier it falls into. For example, a 2 GB installer downloaded 500,000 times in a month moves 1,000 TB.
No request fees apply, so a catalogue of many small files costs the same per TB as one large ISO. Above 1,000 TB the rate drops to $2.50 per TB up to 1,500 TB, and larger volumes are quoted individually from $2.50 per TB. The rate is identical in the US, Europe and Asia. Enterprise terms are available from 100 TB a month, and a quote never raises the published price. Files kept in Cloud Storage cost $0.015 per GB per month.
How is Files on Demand different from a pull-through CDN?
The BlazingCDN Files on Demand CDN imports a catalogue once and keeps the copies, while the Anycast CDN pulls each file from your origin on the first cache miss. With Files on Demand, the origin can go quiet after import. With Anycast CDN, the origin must stay online and reachable.
Lazy import bridges the two models. When a requested file is not yet in CDN storage, Files on Demand fetches the file from a proxy URL you nominate, so the catalogue fills as users ask for files. Each file is replicated across Europe, Asia and America, so one node or region going quiet does not take the catalogue offline. Files on Demand suits catalogues read far more than written, such as software archives served for years. Content that changes daily belongs on Anycast CDN. Both products share the per-TB tiers, from $5 down to $2.50 per TB (as of October 2026).
Can BlazingCDN deliver single files larger than 10 GB?
BlazingCDN delivers single files up to 50 GB each, which covers game builds, disk images, firmware bundles and raw media archives. For example, a 5 GB disk image downloaded 20,000 times moves 100 TB, which costs $415 a month (as of October 2026).
Large files raise two practical issues: origin load and bandwidth control. Files on Demand holds the copy, so the origin is not hit again for each download. Speed limits can be set per resource, or bandwidth can stay unrestricted, depending on whether the catalogue serves paying customers or bulk mirrors. NVMe SSD servers handle the reads, and throughput measured June 2026 on a 100 MB HTTPS download was 1.12 Gb/s in Europe and 1.11 Gb/s in North America. Files above 50 GB need to be split into parts before upload, and the same per-TB rate applies to every part with no request fees.
How do I move a software download catalogue to BlazingCDN?
BlazingCDN onboarding for a download catalogue takes about one hour with an engineer, followed by a KYC check before production traffic. Files can be imported through the API or filled gradually through lazy import from a proxy URL, so nothing has to be uploaded on day one.
A typical migration runs in three steps. First, create the Files on Demand resource and point lazy import at the current download server. Second, switch one product’s download links, or run BlazingCDN as a second CDN behind DNS with a weighted traffic split. Third, compare delivery in real-time statistics during the 14-day testing period on production traffic. The API also manages files, resources and configuration, so release scripts can push new builds automatically. Billing after the test is pay as you go or monthly, with a $25 monthly minimum (as of October 2026). An engineer replies to helpdesk tickets within 3 business hours.
How can I control who downloads files from a CDN?
BlazingCDN Files on Demand restricts downloads with signed URLs, IP address ranges, country blocks and referrer rules, all set per resource. Signed URLs expire after a set window, so a leaked link stops working. IP range rules limit a partner portal to known office networks.
Country-based restrictions block whole regions to meet licensing or export rules. Referrer policies stop other websites from hotlinking installers and running up your traffic. Token authentication adds a per-user check on top. For example, a vendor shipping 20 TB of licensed builds a month pays $92.50 (as of October 2026), and every access control is inside that price with no request fees. Delivery statistics per resource are available in the panel and through the REST API, and raw logs cost $50 per month for audit trails. All transfers run over HTTPS with TLS 1.3 and HTTP/2.
