After (most) basics:

Code:

+-------------+--------+-------------+
| 5    8  67  | 4  1 2 | 9  3   67   |
| 1237 13 4   | 9  6 8 | 17 27  5    |
| 12   16 9   | 7  3 5 | 4  28  1268 |
+-------------+--------+-------------+
| 9    7  12  | 5  8 6 | 3  24  124  |
| 1238 5  128 | 23 9 4 | 17 6   127  |
| 4    36 26  | 23 7 1 | 8  5   9    |
+-------------+--------+-------------+
| 78   2  3   | 1  5 9 | 6  478 478  |
| 6    9  5   | 8  4 7 | 2  1   3    |
| 178  4  178 | 6  2 3 | 5  9   78   |
+-------------+--------+-------------+

Play this puzzle online at the Daily Sudoku site

This still rates as VH on the grade button. But when you remove
the 1s from box1 C1 (column 2 box/line interaction on 1s) the puzzle
comes out and is now rated as easy. Is this one of the occasional
phantom VHs or have I missed something?

Looked at it again. With more basics:

Code:

+----------+--------+----------+
| 5  8  67 | 4  1 2 | 9  3 67  |
| 37 13 4  | 9  6 8 | 17 2 5   |
| 2  16 9  | 7  3 5 | 4  8 16  |
+----------+--------+----------+
| 9  7  12 | 5  8 6 | 3  4 12  |
| 13 5  8  | 23 9 4 | 17 6 127 |
| 4  36 26 | 23 7 1 | 8  5 9   |
+----------+--------+----------+
| 8  2  3  | 1  5 9 | 6  7 4   |
| 6  9  5  | 8  4 7 | 2  1 3   |
| 17 4  17 | 6  2 3 | 5  9 8   |
+----------+--------+----------+




Straightforward XY wing now solves it. (Previously I'd
accidentally filled in a right answer in one square.....)

Hugh, will you edit your posts to reflect the correct date and/or puzzle. The August 18 puzzle is a medium. Thank you.
