CTU Austin was a CTU domestic branch located in Austin, Texas. During Day 3, CTU Austin sent an all-clear report. At CTU Los Angeles, the report was displayed on a monitor, which Ryan Chappelle used to test Tony Almeida's observing capabilities. Tony correctly noticed the all-clear report, which convinced Chappelle he was competent enough to continue his duties. ("Day 3: 9:00pm-10:00pm")
