I haven't been able to access this site from before the puzzle is posted until evening. Has anyone else had this problem.

Hi Bud. A new puzzle arrives each midnight, Sydney time, if that is any help.

Best Regards, Alfred.

Thanks Alfred, it doesn't matter what time the Puzzle arrives when you can't access the site for most of the daylight hours, Florida time. The same thing has happed for the last 2 days.

Hi Bud.
I had trouble accessing the Tough puzzle section on 7 & 8th Sep. I managed to get to it through the back door, by clicking 'Archive'.
Cheers Les.
