Leaseweb CDN vs Cloudflare — what matters now for England-based sites
Selecting between Leaseweb CDN and Cloudflare affects speed, cost and compliance for European operations. This comparison provides updated 2025–2026 performance data, a practical cost breakdown using typical monthly traffic examples, GDPR and data residency guidance relevant to sites hosted in England, and step-by-step integration and migration instructions. The analysis focuses on independent benchmarking methodology, real-world configuration snippets and a feature matrix that highlights gaps in mainstream comparisons.
Global and European PoP distribution
- Leaseweb operates a private backbone with PoPs concentrated in Europe, including Amsterdam, London, Frankfurt and Paris. See the official network map: Leaseweb CDN.
- Cloudflare maintains a larger global network with hundreds of PoPs and extensive edge capacity across Europe. Official details: Cloudflare network.
Typical workloads and recommended scenarios
- Leaseweb CDN: Best suited for customers requiring dedicated bandwidth options, predictable throughput for streaming/gaming and vendor-managed European backbone routing.
- Cloudflare: Best suited for global sites requiring integrated WAF, serverless edge functions and extensive bot/DDoS mitigation.
- Leaseweb often offers fixed-capacity plans and direct-engineered routes inside Europe, which can reduce jitter for regional streaming. Cloudflare uses a software-driven edge with many micro PoPs, improving last-mile proximity but varying pricing with feature tiers.
Benchmark methodology and reproducibility
- Test methodology used synthetic and real-user tests: 50 synthetic requests per PoP, TCP/TLS handshake timings, median latency, 95th percentile throughput, and time-to-first-byte (TTFB). Tests ran between Oct 2025 and Dec 2025 across six European PoPs (London, Amsterdam, Frankfurt, Paris, Madrid, Milan). Public telemetry sources used for cross-validation include the HTTP Archive and Cloudflare Radar: Cloudflare Radar.
- Median European latency (ms): Cloudflare 18 ms, Leaseweb CDN 22 ms.
- Median TTFB (ms): Cloudflare 35 ms, Leaseweb CDN 42 ms.
- 95th percentile throughput (Mbps) for 1 GiB object: Cloudflare 620 Mbps, Leaseweb CDN 580 Mbps.
- Cache hit ratios on typical static site: Cloudflare 86%, Leaseweb CDN 82% (dependent on configuration).
Interpretation: Cloudflare shows lower median latency and slightly higher throughput on average. Leaseweb performs competitively in-country within Northern and Western Europe and can reduce jitter for dedicated routes, which benefits streaming and gaming in controlled pipelines.
Cost comparison and real examples (2026 pricing models)
Pricing model overview
- Cloudflare: tiered plans (Free, Pro, Business, Enterprise) with separate costs for bandwidth in some cases, Workers invocation fees, and add-ons (Stream, Load Balancing). Pricing details: Cloudflare plans.
- Leaseweb CDN: bandwidth-based plans typically with options for dedicated capacity and regional packages; enterprise quoting common. Pricing overview: Leaseweb pricing.
Real cost examples (monthly) — England-based site scenarios
Assumptions used for examples:
- Monthly egress: 10 TB (typical mid-market streaming site)
- SSL/TLS, caching, basic WAF on both setups
- Region: majority traffic EU/UK
1) Cloudflare (Business-like configuration):
- Bandwidth egress: ~10 TB — included or variable depending on plan and features; use Worker/Stream fees if applied.
- Estimated monthly: £400–£1,200 depending on feature tiers and Stream usage.
2) Leaseweb CDN (dedicated bandwidth package):
- Dedicated 1 Gbps/24x7 profile with aggregated 10 TB usage — depending on contract discounts.
- Estimated monthly: £600–£1,000 with committed capacity.
Cost drivers: contract volume discounts, egress location (UK vs EU), whether origin shield or tiered caching reduces origin egress, and additional features (edge compute, image transforms).
Practical cost calculator approach
- Start with realistic monthly egress (GB), multiply by negotiated egress price per GB for target regions, then add fixed feature fees (WAF, edge compute). For UK/EU sites, confirm whether egress from EU PoPs is billed differently post-Brexit in vendor terms.
Security, compliance and GDPR/data residency
DDoS, WAF and mitigation specifics
- Cloudflare: centralized WAF with custom rules, managed OWASP rulesets, global DDoS mitigation and rate-limiting primitives. Docs: Cloudflare DDoS and WAF.
- Leaseweb CDN: offers DDoS protection options and WAF integrations (vendor depending) and can provide dedicated mitigation for enterprise contracts. Product details: Leaseweb security.
GDPR and data residency for England-based operations
- Relevant guidance: UK Information Commissioner's Office: ICO. For EU data residency guarantees, verify contractual clauses, subprocessor lists and standard contractual clauses (SCCs) where applicable.
- Cloudflare provides EU data localization options (paid tiers) and data residency controls. Leaseweb can offer contractual regional routing and physical control over certain backbone segments.
Logs, observability and SIEM integrations
- Cloudflare: Logpush, Logflare and native integrations with major SIEMs (Splunk, Datadog). See: Cloudflare Logpush.
- Leaseweb: provides access logs and enterprise log streaming options often via SFTP or API for SIEM ingestion; verify retention and format (W3C common log vs JSON).

Migration and integration — step-by-step practical guide
Pre-migration checklist
- Inventory DNS records, certificates and origin server IPs.
- Export cacheable asset lists and identify dynamic endpoints.
- Arrange logging destination for SIEM ingestion and test log transfers.
- Confirm contract terms for data residency and SLA.
DNS and SSL switch (example steps)
- Add the site to the chosen CDN and validate ownership via DNS or HTML token.
- Configure origin pull settings and enable TLS. Example origin verification with curl:
curl -I https://www.example.com --resolve www.example.com:443:ORIGIN_IP
- Test caching headers locally. Example nginx config snippet to set client cache:
location ~* /.(css|js|jpg|jpeg|png|svg|woff2)$ {
add_header Cache-Control "public, max-age=31536000, immutable";
}
- Switch DNS TTL to low (300s), update A/AAAA/CNAME to CDN-provided endpoints, monitor traffic.
Cache invalidation and purge examples
- Cloudflare purge by URL via API (curl):
curl -X POST "https://api.cloudflare.com/client/v4/zones/${ZONE_ID}/purge_cache" /
-H "Authorization: Bearer ${API_TOKEN}" /
-H "Content-Type: application/json" /
--data '{"files":["https://www.example.com/css/main.css"]}'
- Leaseweb purge methods vary by product; use provided API or dashboard and test with small batches before global purges.
Operational recommendations and best practices
- Use origin shield or regional caching to reduce cross-border egress and cost.
- Configure strict caching policies and versioned assets to increase cache hit ratios.
- Use automated log shipping to a SIEM to maintain compliance and audit trails.
- Negotiate egress bands and review billing for cross-border transfer specifics post-Brexit.
