Yesterday and today the site has been very slow to respond to creating and starting puzzles. It has also been very slow to respond to decide if the puzzle is correct when finished. This causes slow solve times and many times when I don't bother to start new puzzles as the times would be very slow and not worth the time to solve them. Other times the site locks up and goes offline. Imagine how you would feel if this happened to you. No other sites I go to have had this problem, so it has to be on your end Admin. Have others had this problem. If it hasn't affected everyone else, it makes it useless to compete against others who have no problems with this.
