Strange. We're using http://download.eclipse.org/releases/oxygen/ as a location for our target platform. In a build that is run on a Hudson build slave on an AWS EC2 instance, in two consecutive runs we see the first access to the p2 repository succeeding:

[INFO] Fetching content.xml.xz from http://download.eclipse.org/releases/oxygen/201804111000/ (863.03kB)
...

Then in a second part of the build job we keep getting:

[INFO] Fetching p2.index from http://download.eclipse.org/releases/oxygen/
[INFO] Fetching p2.index from http://download.eclipse.org/releases/oxygen/
[INFO] Adding repository http://download.eclipse.org/releases/oxygen

Unable to read repository at http://download.eclipse.org/technology/epp/packages/oxygen/content.xml.xz. connect timed out -> [Help 1]

When the instance was in this state, also a wget for http://download.eclipse.org/technology/epp/packages/oxygen/content.xml.xz would time out whereas the same wget from some other network worked.

Are there any rules in place that could lead to subsequent accesses to the p2 update site coming from the same IP address being blocked? This would really be a problem...

This isn't really an Oomph question. In any case, part of such problem is that the download.eclipse.org server transparently redirects requests for repository metadata to mirrors. You can't control this because it's simply server behavior. Depending on where you are located (mostly the time zone) and perhaps on other non-deterministic factors of where the server redirects, you may be redirected to a mirror server that's having problems, or has stale content as in this bug that I still have open:

https://bugs.eclipse.org/bugs/show_bug.cgi?id=539316

The stale content issue is highly reproducible. In any case, mostly transparent mirror redirection is good to help keep download.eclipse.org from being overwhelmed, but it can and does also cause problems because the mirror to which the server redirects can have problems too...
