All is not well when a validator is not properly connected, e.g: of things that might happen: - Finality might be slightly delay because validator will be no-show because they can't retrieve PoVs to validate approval work: #8915. - When they author blocks they won't back things because gossiping of backing statements happen using the grid topology:, e.g blocks authored by validators with a low number of peers: https://polkadot.js.org/apps/?rpc=wss%3A%2F%2Frpc-polkadot.helixstreet.io#/explorer/query/26931262 https://polkadot.js.org/apps/?rpc=wss%3A%2F%2Frpc-polkadot.helixstreet.io#/explorer/query/26931260 https://polkadot.js.org/apps/?rpc=wss%3A%2F%2Fpolkadot.api.onfinality.io%2Fpublic-ws#/explorer/query/26931334 https://polkadot.js.org/apps/?rpc=wss%3A%2F%2Fpolkadot-public-rpc.blockops.network%2Fws#/explorer/query/26931314 https://polkadot.js.org/apps/?rpc=wss%3A%2F%2Fpolkadot-public-rpc.blockops.network%2Fws#/explorer/query/26931292 https://polkadot.js.org/apps/?rpc=wss%3A%2F%2Fpolkadot-public-rpc.blockops.network%2Fws#/explorer/query/26931447 The problem is seen in `polkadot_parachain_peer_count` metrics, but it seems people are not monitoring that well enough, so let's make it more visible nodes with low connectivity are not working in good conditions. I also reduced the threshold to 85%, so that we don't trigger this error to eagerly. --------- Signed-off-by: Alexandru Gheorghe <alexandru.gheorghe@parity.io> Co-authored-by: Bastian Köcher <git@kchr.de> Co-authored-by: cmd[bot] <41898282+github-actions[bot]@users.noreply.github.com> (cherry picked from commit c7f9908)
