Testing TDE R14

Hello, I would really like to do more testing of TDE R14 nightly builds on Ubuntu 13.04, but the TDE servers seems to be completely overwhelm since a few week, especially since Ubuntu nightly builds LiveCDs are available. When I want to update to the latest nightly build, it downloads at less than 56k Internet speed, so I often have to cancel the download because I don't want to wait for 15 hours for a it. Is there some ways that could be considered to make faster the TDE servers? In the list of distros where nightly builds are available, I see completely outdated versions of linux distributions. Is it still necessary to build nightly builds for obsolete versions of Ubuntu, as an example? Also, maybe a weekly Ubuntu nightly build LiveCD could be enough for its purpose, making the TDE servers save on bandwidth and improve its performance. Thanks! -Alexandre
