On OZON you ll find a file called HECNETUTCMAP1.GIF
It puts nodes I had default decnet access to in UTC timezones.
The picture is considerably more weird than the earlier excel art .
It appears that bizarrely, there are only three direct links between
areas which are in the same timezone as each other. The majority of links
are across several timezones and there are no links at all between the areas
in the UTC+0 timezone.
Thanks for your work putting the map together Hans.

Peter Coghlan.
