That explains a lot !Then you only have 30 sec timeout by default. I think you can modify the timeout by setting the property sun.net.client.defaultReadTimeout.

I think the deeper problem here is that this repository hasn't been configured with a mirrorsURL. I have entered this bug:
https://bugs.eclipse.org/bugs/show_bug.cgi?id=276300
If mirrors were present you would get very different behaviour, since we retry once per available mirror. With no mirrors and a two minute timeout contacting the main server, I'm not sure we could do a lot better. Henrik described the problem very well - there is no perfect retry policy that makes sense for both headless builds and end users, so it's a difficult problem.
I know that there's been some improvements in this area since M7 which
I'm currently using but I thought I might ask anyway. What kind of
socket timeouts do we have and do we make any attempt to retry when a
socket timeout exception is thrown?
I tried installing the org.eclipse.platform feature several times. I
always ran into a SocketTimeoutException (see stacktrace below).
Apparently it tries to download the packed file first and then the jar
file. If neither succeeds, the installation fails. I first tried this on
my local machine. I almost always failed so I decided to move to
build.eclipse.org. As it turns out, it fails there too. So what's going
on here? Does it contact mirrors that fails or what?
I'm explicitly trying to install from
http://download.eclipse.org/eclipse/updates/3.5milestones/S-3.5M7-I200904302300.
Here's the stack-trace that I'm getting 7 times out of ten (the bundle
that failes question vary):
