In this case, it was probably that clang-devel, llvm-devel, and lldb-devel were updated, and this produced many large binaries (six 900MB binaries for clang-devel; seven 750MB binaries for llvm-devel; two 275MB binaries for lldb-devel).

We asked all of our existing mirror providers last year and were not able to find such an arrangement. What we found was that Friedrich-Alexander-Universität was willing to become our master public rsync server and the origin server for distfiles and packages that feeds our CDN. So that is the arrangement we currently have, with them pulling the files from my private rsync server every half hour. The problem arises when several gigabytes of new files have been created in a short time, since the current rsync run must complete before a new one will start.

The buildbot setup currently consists of four Xserves and a Power Mac G5.

Does your consumer Internet connection allow running a publicly-accessible server?
We do currently have a single static IP with ports 80, 443, and 873 open for the buildbot web site and the rsync server. Although it is not entirely working at the moment, the server is also supposed to be sending emails on failed builds; my understanding is that sending mail from a dynamic address makes other servers more likely to classify the message as spam.
