Code Recommenders cannot download its model repository index,
see the attached screenshot.

It definitely isn't a network problem, probably a server-side
one. I followed Eclipse with Wireshark. It tries to download:

1. http://download.eclipse.org/recommenders/models/photon/org/eclipse/recommenders/index/0.0.0-SNAPSHOT/maven-metadata.xml
2. http://download.eclipse.org/recommenders/models/photon/org/eclipse/recommenders/index/0.0.0-SNAPSHOT/maven-metadata.xml.sha1
3. http://download.eclipse.org/recommenders/models/photon/org/eclipse/recommenders/index/0.0.0-SNAPSHOT/index-0.0.0-20171110.192552-1.zip

The first two items pass OK. The last one starts with Eclipse's
request, then the server responses with "206 Partial Content"
and Eclipse immediately closes the connection. Truth be told,
Eclipse's request doesn't ask for any specific range; I'm not
sure if the server's response is correct in such a case.

It looks to me like there was some change on the server side
and the client code in Recommenders cannot cope with it. FWIW,
my wget cannot download the file either, obviously fooled by
the same "206 Partial Content" response.

Wget also fails here.

Also, while Firefox downloads the file, the download results in a corrupt ZIP file that fails to extract.

Hence, this looks like a server problem, not one in Code Recommenders. Reassigning.

This is a bad server response. Looking into it.
