Totally possible that it froze after the tee on the way to the upstairs. I'd run some hot+cold water slow for a couple hours from the tap that is still working and crack open to do the same on the frozen upstairs. Goal is that:
a) if the line is indeed frozen, the increased pressure from the freeze doesn't blow anything out (by having upstairs cracked)
b) the radiant heat from the working line (by having hot+cold running - we're talking over level faster than a drip) helps thaw out the frozen part and and frozen tap will work itself open if left open a tad.

Yeah, borrowed a corworkers propane heater and that got it flowing. Not sure if it was at that T or somewhere behind the wall but will leave the water flowing tonight.
Pray for no burst pipes!
