Will be doing a CKDB restart after 01:00 UTC - a bit after 01:20 UTC I think it will be.
No miners will be affected.
Web site will show lotsa '?' ... for about 15-20 minutes.

This will be a longer than normal restart to get a lot more logging of the sequence numbers that I'm trying to resolve the issue in the new code.
It will actually be 2 restarts - so about twice as long.

It will be the shift summary after 01:00 UTC which should be a bit after 01:20 UTC
