after #9981

[soc1c]

Callisto #9534

callisto full 25 peers pass no snapshot peers

@yograterol are you guys operating any parity-ethereum bootnodes that could generate snapshots?

POA Network #9413

poacore full 2 peers pass can't seem to find more peers / no snapshot peers

@phahulin do you have some updated bootnodes for us?

Clique chains #9981

kotti full 5 peers pass no snapshot peers
goerli full 5 peers pass no snapshot peers

@fevo1971 can you help me checking if our clique bootnodes generate snapshots (checking the logs, checking if there is a snapshot on disk)

@soc1c thanks for reaching out.

• for POA Core list is unchanged,
