Hi
For the past few weeks I've been getting random blue fill at high zoom
levels. Is this caused by the coastline being broken again?
When it happens, right-click the browser and "view image". You'll get a
URL something like:
http://c.tile.openstreetmap.org/14/8126/5331.png
Adding /status to the end shows when it was last generated:
http://c.tile.openstreetmap.org/14/8126/5331.png/status
Adding /dirty to the end schedules it to be rerendered
http://c.tile.openstreetmap.org/14/8126/5331.png/dirty
(when this actually happens depends on how busy things are).
If a "flooding" problem has been fixed, this rerendering will fix a
left-over tile that hasn't been scheduled to be rerendered yet.
More details here:

What's the best way to prevent this happening? Is there a way to get
notification (email/text etc) if a specific entity gets modified?
Geofabrik's OSMI coastline view should show problems:
http://tools.geofabrik.de/osmi/?view=coastline&lon=-3.92892&lat=54.54719&zoom=5&opacity=0.63&overlays=coastline,coastline_error_lines,line_not_a_ring,line_overlap,line_invalid,line_direction,questionable,coastline_error_points,unconnected,intersections,not_a_ring,double_node,tagged_node
Cheers,
Andy
