They have been reporting on the TV this morning about a worldwide Microsoft IT outage which is causing disruption at airports, railways, banks etc so I decided to see if I was affected. I switched on my Linux laptop and created the puzzle below. I connected to the Internet and graded it at SudokuWiki then I published it on Google's Blogger platform. Facebook, Twitter and Linkedin are up so I should be able to share it too:
Here is a string which you can copy to work on this puzzle online:

This puzzle has a Hodoku grade of Hard (1376) so it would have qualified for inclusion in my book as all the puzzles there have a Hodoku grade between Hard (1000) and Hard (1999).
Andrew Stuart gives it a grade of 201 (Very Hard) on his main page but calls it Diabolical when you look at the solve path.

I created this puzzle just now. I was trying to create an extreme one but, after 75 attempts I had not found what I was looking for so I chose this one instead. It has a Hodoku grade of Hard (1508) so it is typical of the puzzles in my book, which all have a Hodoku grade between Hard (1000) and Hard (1999).
