Reliable block production is job #1 for a Steem witness, especially for someone in the top 20.

I feel it's the same responsibility for backups too. What happened during that crisis was a testament to that. While some top 20 witnesses were up and running, some were forced to replay, and the backups who updated, without a forced replay, where helping restore network participation, i.e. they became top 20 temporarily. In the end, big or small, we're all valuable for the network.

A couple witnesses jumped the gun, causing all other witnesses to miss their scheduled amount of blocks.
