I couldn't make any outgoing calls yesterday near Courthouse Square in Santa Rosa. Tried restarting my iPhone twice, no luck. Went into the Apple Store in the Mall, got in line to see a tech, tried to make a call and no problem. Walked out of the Mall still on the same call and as soon as reached the Courthouse Square area, the call dropped. Walked back towards the Mall and was able to call my friend back. Very weird to find an outage downtown like that.
