Well, to stop all suppositions…
After like 2-3hours I got suspended, even before receiving the “Node offline” email. Something is wrong with these audits…
But… @Toyoo you are a Code Wizard level 50. The node is now VETTED. 
WARN reputation:service node scores worsened {"Process": "storagenode", "Satellite ID": "12L9ZFwhzVpuEKMUNUqkaTLGzwY9G24tbiigLiXpmZWKwmcNDDs", "Total Audits": 141722, "Successful Audits": 140684, "Audit Score": 1, "Online Score": 0.9971701333830808, "Suspension Score": 0.28895593993885077, "Audit Score Delta": 0, "Online Score Delta": -0.00012722646310425745, "Suspension Score Delta": -0.7110440600611492}
So, seeing that score, it could reach 0% in less than 24h. Could you be DQ-ed so quickly? Why?
What’s the difference between blacklisting the sat and being offline because of some blackout?
