What's your thinking behind the fetch snapshot case? The problem with doing this is that it will create holes in the local rocksdb ledger data. When fetching data over RPC, we only fallback to BigTable for slots that are older than the first local rocskdb slot. So holes in the local ledger will not fallback to BigTable.
I'm thinking the rm -rf ledger/ case is the only one we need

How about now @mvines?
Or do you think 1,500 is too aggressive?

1500 seems like a good place to start at least

Can you please turn 10.142.0.4 into a constant, so it's more clear what host this is

I'm a fan of adding set -e to the top of these kinds of scripts so they bail on failures (usually atleast, there's lots of caveats with set -e) instead of stumble along and start causing splash damage

Should we emit a metric here so we can get flagged in pager-duty and or on http://bit.ly/solana-cluster-sanity?
Emiting a metric is easy, start by sourcing this script:
