SRE Team Update

High level summary​

The SRE team continues work on Cardano environment improvements and general maintenance.

Some notable recent changes, updates or improvements include:

  • All environments have been upgraded to cardano-node 9.2.1.

  • Cardano-faucet 9.2 is available and deployed which is compatible with node 9.2.x and has fixed ipv6 functionality.

  • All deployed machines now default to nix 2.24-maint after an upstream bug causing a hash miscalculation in submodules has been fixed. Nix 2.21 forward required some rework of the colmena deployment recipes as dirty git trees now force an impure colmena deployment.

  • To ease the process of upgrading cardano-parts, releases will now be made instead of only PR merges with migration notes.
