Description
Hi, It seems that there's an intermittent tile map server problem where this online tool that uses OSGEO mapping is not correctly showing the tiles. This tool has been working without a hitch but recently soemtimes experienced intermittent problems when vmap0.tiles.osgeo.org doesn't respond with a tile image. http://portal.nccs.nasa.gov/cgi-lats4d/webform.cgi
I've tracked it down to this URL calls failing on occasion. Would you know if you guys are having service issues for vmap0 tile service or is it caused by something else, maybe a firewall blocking access from nasa servers?
I'm using the exact same link from my browser and it sometimes shows a tile while sometimes it throws an "Internal Server Error". Any help would be appreciated.

I gather from #1264 we are running the vmap0 service on webextra and sphere (@telescience) and Martin seems knowledgable (+cc).
Service is (lightly) documented at:
http://wiki.osgeo.org/wiki/WebExtraVM#vmap0.tiles.osgeo.org

This url, which I think is hardcoded to webextra, does seem to work.
Checking pairnic, I confirm that mstest points at webextra. There are three round robined settings for vmap0.tiles.osgeo.org:
vmap0.tiles » 137.110.112.116 vmap0.tiles » 137.110.118.253 vmap0.tiles » 140.211.15.68
The last is webextra - I presume the other two are at telescience. Martin, any thoughts? Are these things I can help update?

My fault, I didn't realize that a few libraries got lost when updating two of the tile renderers to latest Debian. Might be fixed now, please test again.
Sorry, Martin.

Ouch, these tiles are looking very ugly, will remove the two broken renderers from DNS until real fix is available, Martin.

I have confirmed getting a 500 for this example url:
http://vmap0.tiles.osgeo.org/wms/vmap0?LAYERS=basic&SERVICE=WMS&VERSION=1.1.1&REQUEST=GetMap&STYLES=&FORMAT=image%2Fjpeg&SRS=EPSG%3A4326&BBOX=-180,-90,0,90&WIDTH=256&HEIGHT=256
Digging a bit deeper.
