Monitoring
Root cause has been identified. If you are a node operator with `db_backend = "goleveldb"` and `app-db-backend = ""` set in app.toml, please update your config, specifying `app-db-backend = "pebbledb"` instead.

This issue stems from our use of the `types.DBbackend` compile-time variable, which was removed in Cosmos SDK v0.47. The value derived for `app-db-backend` on nodes that do not specify a value effectively changed between ZetaChain v18 and ZetaChain v19. Explicitly setting `app-db-backened = "pebbledb"` should enable goleveldb based nodes to return to service.

Identified
Block production has resumed for the Athens Testnet.

Root cause is not known, but appears to be isolated to nodes with "db_backend = goleveldb" set in config.toml.

CrossChain transactions are currently blocked, but will resume within the next few hours after testing is completed.

Update
The network has just under the 2/3s majority needed to restart. No root cause for failed upgrades on some validators has been identified. We have made contact with several validator operators and are actively working to them with them to restore their nodes.

We are continuing to investigate the root cause of the failed upgrades.
