[arch-general] mirror.cs.vt.edu outdated

Hello, this mirror has an old lasysync of 1279951267. Googling this number returns a few results for other mirrors at this time. What does it mean? Lastly, what mirror is the "most trusted"? I trust vt.edu, their uptime has been wonderful until it stopped updating packages. I don't want to use the archlinux.org server, as it's limited (and you guys probably don't like the extra load). Thanks.
