Dear friends,

We should continue to be careful downloading Keplerian elements from 
Space-Track.org.  All of the files there are empty, so if you have an 
automated downloading program like Nova, it will overwrite its Keps with 
zero data.

I wrote to Space-Track and they replied:

I don't know how this "outage" will affect other distributors of orbital 
elements (i.e. Celestrak).
