Less than 100% online due to unexpected power cut - short + long term impact?

(First off - yes, I know uninterruptible power supplies exist.)

A power cut happened unexpectedly about four days ago and power to my RPi that runs my Storj node was off for about 4 hours. Since then, my “online” stat for us1.storj.io is at 92.86% and us2.storj.io is at 92.31%. The other four are all still at 100%.

Of course I understand that since my node was offline for a time, my online stat will be less than 100%. But it’s raised some questions I can’t find answers to:

  1. 92.31% of what? 92.31% online = 7.69% offline; 4 hours is 7.69% of 52 hours. Why 52 hours? My node has otherwise been running constantly since early April. Four hours as a percentage of 730*2 = 1460 hours is less than 0.3%

  2. The two percentages (92.86% and 92.31%) haven’t changed since they first dropped from 100%. But as time passes, surely the amount of time I was offline for, as a percentage of whatever timescale represents 100%, would reduce?

  3. On that subject - what timescale do the Retention and Audit stats represent? Today? This week? This month? Forever? (And whatever the answer to this - how does that explain (2) above?)

  4. And, as per the title of the post, what are the likely short and long term impacts of this? I’m not expecting to make enormous returns from Storj but I’ve got 6TB available which I’m happy to commit for the long term; but if this will curtail the usage of my node long term, I would need to question whether the long term commitment is worth it.
