Over the last 3 months (January, February, March 2022) we've provided a scalable free public API service so that everyone can access public pools of managed Polkadot, Statemint, and Westend nodes. This provides the following three outcomes:
This last quarter has been huge for Polkadot and OnFinality, the demand for our services continues to be another unprecedented period. January had a larger activity than the rest of the quarter which also had our highest daily Polkadot response count (for Q1) of over 340 million responses in a single day. Raw data is here.
This quarter was all about service stabilisation as part of the promise we made to this ecosystem to provide enterprise grade services to the community. Our services all exceeded our 99.9% target, with 99.99% uptime for Polkadot over the last 90 days. This is an important measure as we surpassed our largest ever day, with over a billion API responses processed by our service in a single 24 hour period in late January.
You’ll note that there was a significant increase in the amount of data egress over the previous quarter (55% growth to 110TB). We’ve been constantly scaling our nodes to meet this rising level of demand while maintaining our target 99.9% uptime (actual was 99.99%). We are currently working on new load balancing solutions to better route this traffic to different node types and expect that we will soon be able to handle more traffic with less resources.
Between 2022-01-01 and 2022-03-31 our Kusama API service has:
