I sometimes find modules with outdated urls. I can maintain urls I use by 
simply using them. The problem is with devels, if they include urls in 
modules. There is more chance to catch working mirror on 50 mirror list than 
on 5 mirror list. The mirrors are usually important for big files. Lunar is 
designed in such well way that tries next url if previous failed. The only 
change I propose is to try local mirrors first and next use the rest.
They only one problem with mirrors I had was slow update time. I had to wait 1 
day to see update on mirror. I think most people do not do lunar update 
everyday. Module update also takes some time. So this problem is almost non 
existent.

Yes. But it could start with local or neighbour one. I see many German urls in 
modules, but US urls are placed first so do not have possibility to use those 
closer and faster urls. There is nothing wrong with US servers but they are 
far away.

Could you drop me example file via e-mail. I couldn't find any SDK on lunar 
website.

Sourceforge is working good. It automaticly uses closest to me mesh form 
Germany.

This is not good idea. There is no mirror which mirrors everything.

... for people connecting outside Poland. This is local mirror, foreigners 
have ultra low priority. They can connect when almost nobody uses it. But 
this never happen. Thanks to such traffic filtration server is very fast.

BTW How to setup lunar to use .de mirror. I set .de mirror in LRESORT but it 
still lunar update downloads moonbase from main site.
