If you are a server admin and pointed your sv_curl_defaulturl to http://141.2.16.3:7780/nex/maps/inofficial/ or http://141.2.16.3:7780/nex/maps/attic/, please do not run these maps on your server on Monday and maybe still Tuesday. I will reinstall the operating system on the server and in the meantime, the map downloads from it won't work.
If you want to mirror them somewhere, please download the full package from http://mensa.ath.cx/~polzer/temp/nexmaps.zip and extract it on some server. If possible, post the URL here then. Thanks. This URL will stay up during the reinstall, but probably I will delete it in some weeks.
