intermittent 400 errors from download.eclipse.org

Summary

It seems I am seeing an increase in 400 errors from download.eclipse.org causing random failures in many builds.

fyi @emerks

Steps to reproduce

Run lots of builds, some fail

What is the current bug behavior?

400 errors

What is the expected correct behavior?

100% uptime ;-) - I know that is unrealistic, and I don't know what the current failure rate is, only that it seems to have gone up. 2 of my last 3 PRs in the last couple of days had the same error.

Relevant logs and/or screenshots
