Um, what are you talking about? It is near Jollyville which is at the North Austin city limits. Get on 35 and wait in traffic in Temple and you'll figure out how far Dallas is away.
In terms of terrain and culture, once you're in Jollyville / Round Rock, it's not really Austin any more, it's indistinguishable from generic city USA.
Do you know where it is? I can't find any info on the exact location.
I assumed somewhere near Round Rock for the proximity to the old tech workforce but that was just a guess.
Article just says within a mile of their current campus
my source says intersection of Dallas Drive and Parmer Lane
