Ocean Grid is now four years old! Hooray! :-D

The grid was created on 16 March 2010.

However, the grid's home region, Annwfn, is the oldest region now on the grid, created on 21 October 2010 at 11:26:24 am. Of the others in the group of four home regions, Gododdin was created just under half a minute later at 11:26:53 am, Celyddon was created under four minutes later at 11:30:08 am, and Aeron was probably originally created at almost the same time, though the present region was re-created over 77 days later on 6 January 2011 at 11:50:07 am.
