It appears that the Subsim server is over quota again - both GW and NYGM files are not available. I have asked Neal to confirm.
The alternate mirror is the main location at the moment (I never have speed problems - perhaps try at "offpeak" times). I am waiting to hear back from a few other potential mirror site hosters as well, although if anyone wants to volunteer space (but not Rapidshare, FileFront or FileFactory
), please let me know.
