It's where the coastline shapefile generation has gone wrong: it
thinks that area is sea. Because we use "inverted" coastlines compared
to the main osm/mapnik layer, errors in the coastline through up
different results between the cyclemap and the other mapnik layers.
I'll regenerate them some time soon and see if that fixes it.

Yeah, about 50% of the time the server is too busy serving tiles and
rendering new ones, and can't keep up with demand. It's too popular,
perhaps :-)
