The tool kmlexport (http://tools.wmflabs.org/kmlexport/) is heavily used in both Wikipedia and Commons (see templates in wikidata:Q5845436).
I guess there are hundreds of thousands of articles that have a link to this tool, German Wikipedia already has more than 100,000 transclusions of the corresponding templates.
But the tool is down a lot ("No webservice"), complaints are getting more and more (enwiki, dewiki and commons is what I know about).
After being restarted on the toolserver, it doesn't take too long and the tool is down again. (See also wikitech:Moving kmlexport to trusty? -> ''kmlexport has been dying a lot recently''.)
Isn't there any possibility to make this tool run more stable?
