Around 11:45 PM night of April 7, 2017, the outdoor weather warning sirens began sounding around Dallas. It was a clear night, with no severe weather for hundreds of miles. Confused citizens called 911 to report or ask about the sirens, clogging lines and leading to
wait times exceeding six minutes. Others (like myself) called police dispatch lines and were told that nobody knew what was happening. Local news and the city were silent on all media channels – TV, web, Twitter, email, the Amber Alert system. The only sound we heard were the sirens, off and on for over an hour.
By the morning, it was reported that persons unknown had hacked into the warning system and activated the sirens. They had to be disabled manually by fire crews and would be unavailable for a few days while they investigated, updated and re-enabled the system. Thankfully, there was no severe weather predicted for this time.
