Global content delivery,
engineered for speed.
Diamond CDN accelerates websites, APIs and media for teams that cannot afford to be slow. 280+ edge locations, HTTP/3 by default, and a real 99.999% uptime SLA.
Everything a modern CDN should do
We obsess over latency, uptime and security so your team can focus on the product.
Edge caching
Intelligent TTL and stale-while-revalidate keep your origin quiet and your users happy.
DDoS protection
Always-on L3–L7 mitigation. 8 Tbps of scrubbing capacity across the whole network.
HTTP/3 & QUIC
Faster handshakes on lossy networks. Enabled by default — no extra config.
Anycast routing
Every POP announces the same IP. Users are served from the closest healthy edge.
Real-time analytics
1-second granularity. Cache hit ratio, origin latency, status codes — all in one place.
Zero-trust edge
mTLS, WAF, bot management and signed URLs built into the same control plane.
How it works
Onboard in minutes, not days.
Point your DNS
Create a CNAME to edge.diamondcdn.net or use our nameservers. We handle the rest.
Enable caching
Default rules cover static and HTML. Tune with cache keys, purge API and custom rules.
Ship
HTTP/3, TLS 1.3, Brotli and the full WAF are on by default. Zero downtime rollouts.
Loved by fast teams
“We cut our p95 TTFB from 340 ms to 41 ms after moving to Diamond. Cache hit ratio jumped to 97% in a week.”
“The DDoS story is what sold us. We saw 1.2 Tbps peak during a launch and didn't notice it.”
“Support actually knows networking. We migrated 40 domains in a single afternoon.”
