Routing & connectivity

The perfect mix of multiple Tier 1 transit providers and private peerings with local networks in each location, combined with latency-based routing ensures that all packets are delivered seamlessly.

Latency-based routing

Thanks to real-time monitoring of 150,000+ SRC/DST IP addresses, we gather detailed data about latency and quality of connection from all of our locations. More than 600,000 netflows are being analysed every second. This enables us to automatically direct your users to the lowest latency endpoint.

Our routing process is fully-automated and has proven to be faster & more reliable than Anycast routing used by most CDNs.

Access to all major carriers and ISPs

The network topology combines upstreams to top 14 transit providers and direct connection with a ~ 100 local networks worldwide.

Network teams

Automated routing processes are under 24/7 supervision of our network engineers.

Network Development

My team precisely plans and executes development of the CDN77 network. From access to the edge, physical fibers to DDoS protection – it's all our responsibility. Our network is fully redundant and it's based on Arista network hardware.

There is one single priority above all that drives our decisions and steps while extending and maintaining our network – uncompromising quality, without exceptions. We consider the work we do as a way of life rather than a day job.

Jiri ProchazkaHead of Network Development

Data Centers Ops

The DCs ops team takes care of CDN77 servers in data centers around the world. It's mostly about HW shipping, new server installations, cabling, SSDs, and other HW changes. We handle both carefully planned upgrades and also situations where immediate solutions are needed.

Photos of our perfect cabling are popular on Reddit. No matter whether we use remote hands or travel to a location personally, any DC job needs to be fast and precise.
