 Testground is a platform for testing and benchmarking distributed systems. We used it before to work on massive improvements to IPFS DHT, Filecoin Network, and libp2p. This year, the [IPDX team](https://pl-strflt.notion.site/IPDX-122073392dce454e9ca4b87231034483) re-ignited the project. We started two collaborations, created a new use case for interoperability testing, and welcomed new users and contributors.
 
 Now that the end of the year is near; it is time for a “bragging session” and to share our master plan to take over the CIs of the entire Protocol Labs Network!
