Web host Rackspace evacuated its employees late Thursday, Dec. 2, after receiving a bomb threat against its Texas office complex.

The police and Fire Departments completed a sweep of the facility and determined that it was safe for employees to return to work Friday morning.

“Our Rackers (employees) are our first priority, and we appreciate their patience as we took precautions and evacuated the Castle facility to ensure their safety,” says Samantha Moreno, spokesperson for Rackspace. “We take these threats seriously and we appreciate their patience as we took precautions and evacuated the Castle facility to ensure their safety.”

At this time there is no word whether the bomb threat was the work of a bored, or deranged person, an “ex-racker” (or current racker with a hot date), or a disgruntled client.
