That will roughly be at 01:45 UTC (about an hour from now)
No miners will be affected.
I'm adding changes to reduce the amount of RAM required during a CKDB restart so I can do the luck report change I mentioned before.
It would effectively mean running CKDB twice on the server, once as normal and a second time for the duration of generating the luck report, so I need to get the memory footprint on the main CKDB down more, to be able to do that, with recent changes.
Mining is unaffected, API access is OK, but web logins are currently not working.
I'm working on sorting out the web login problem ...
Nothing major, but the web password hash (only) that is being passed to CKDB is being truncated due to the last change.
I've patched CKDB on the server to fix it and will restart CKDB (in about 1 minute ...)
I'll code a better fix for it later, but this one is OK and gets logins working again.
The previous restart drastically reduced restart memory usage, so that was good at least
CKDB restart in 1 minute.
