Take a look at this:
Suspension Score
Finally, the suspension score is visible on the storage node dashboard. The calculation is the same as for the audit score. A score of close to 100% is good. You will get suspended for a suspension score below 60% and disqualified for an audit score below 60%. Successful audits will increase both scores. Most audit failures will decrease the suspension score except missing or corrupted pieces. These 2 failures will directly impact the audit score instead. A storage node can recover from suspension mode. Disqualification is permanent.
