+## Roblox
+
+[Roblox](https://roblox.com/) builds the tools and platform that empower people to create their own immersive experiences,
+so that any world they can imagine can be brought to life.
+
+With more than 200 million active monthly users, Roblox is one of the most popular gaming platforms on the Internet.
+The company started with Prometheus and InfluxDB for observability, but as volume continued to build,
+Roblox eventually adopted a time-series database called VictoriaMetrics.
+
+That sudden growth coincided with a substantial rebuild of Roblox’s observability system, which informed internal users about
+everything from the condition of Roblox application servers and storage infrastructure to the number of players and player experience.
+
+The original observability system was largely homegrown, consisting of some open source software and internally developed tools.
+It was based on a decentralized model and leveraged individual Prometheus and InfluxDB instances to store data streaming
+in from the infrastructure and the platform, which internal Roblox users analyzed using Grafana and an internally developed tool called RCity.
+
+From a usability perspective, there was no central repository for data or analysis, and engineers had to jump around to different tools
+to get what they needed. It also hurt Roblox’s flexibility to know how the platform was working in a new region or a new country.
+
+And while the simplicity of storing data in key-value pairs aided visualization, it made doing in-depth analysis a real pain.
+
+Lastly, the homegrown observability system hurt reliability for Roblox.
+
+By all accounts, the move to VictoriaMetrics and Grafana has been a success. With a centralized telemetry database and visualization system,
+Roblox engineers don’t have to hunt around for different tools when problems arise, which was source of delay before.
+The new setup has also helped Roblox deliver 100% availability for three straight quarters, despite moving a massive amount of data.
+
+Numbers:
+
+- 200 storage nodes in VictoriaMetrics cluster
+- Active time series: 5 billion
+- Data ingestion rate: 120 million data points per second
