Negative. You will still get suspended and you will still get that information a few hours later than you might expect. The storage node dashboard is not showing live data. It requests the data from the satellite with a high interval. That high interval is the reason why you might see 100% → 60% in just a second.
If you want early email notification I would recommend this: [Tech Preview] Email alerts with Grafana and Prometheus
No. 29 pieces are required in order to have a valid audit result. If the satellite is unable to connect to the storage nodes we will ignore the audit result and assume the connection problem is on our end.
Do you mean the storage node dashboard API? I am not sure. We can try that out on Monday if you like.
How should the satellite garantee durability? Should we send the first 1000 files to /dev/null and just ignore any audit errors we might get back?
Your screenshot is telling a different story. If the satellite is unable to connect to you that would impact your online score. The satellite was able to reach you but you returned no data within 5 minutes (3 times in a row) or an error message.
