Our Infrastructure

Exceeding the highest standards

Our presence in 47 data centers across 15 regions is unmatched. Wherever you are in the world, we’ll make your search ultrafast and reliable!

DSN - Distributed Search Network

Easily distribute your search engine on up to 15 regions worldwide.

Our Distributed Search Network allows you to automatically replicate and synchronize your data across 15 regions, and search queries are automatically directed to the closest data center.

With our DSN, network latency is dramatically reduced.

Unique High Availability

We are consistently striving for 100% uptime and take our redundancies quite seriously.

Server Redundancy

Your data is replicated on at least 3 high-end servers that can independently handle each query.

Even if 2 servers are down, your search engine is up and running.

Provider Redundancy

These 3 servers can be hosted by up to 3 different providers, across 3 data centers, through 3 autonomous systems, enabling multi-region reliability in a single region.

Even if an entire data center is down, our provider redundancy ensures service availability.

DNS Redundancy

We have introduced a DNS fallback strategy that relies on a second completely independent infrastructure.

A broken DNS resolution will not stop your queries from reaching our API!

Ensuring Business Continuity

Information security is at the top of our minds since day one.


  • Everything is considered as unsecure, even communications within the same rack are encrypted.
  • Only ports HTTP and HTTPS are publicly opened.
  • Servers are always running on the latest stable version of nginx web server.
  • Infrastructure is protected by multilayer access control.
  • Servers located in datacenters built following the industry security standards.
  • A continuous security testing through a public bounty program is opened on HackerOne.

No need to worry. We keep your data safe!

Disaster Recovery

An incremental backup of your data is built every couple of hours.
For a faster service recovery, a client-side encrypted copy of the data is also sent to the closest AWS S3 region.

No matter what, your data won’t get lost!


We are passionate about sharing how we build and fix stuff.
