We run into issues where downloading updates are slow while running update tests. Generally, we shrug our shoulders and don't know if it is the mirror, LAN, region, or what. We need to have multiple machines at multiple locations, preferably in and out of colos. This will allow us to diagnose the cause of slowness, switch to faster locations, test more of the mirror network, and pipeline more testing.
Project never went anywhere; reopen if priority increases.
