Intrado has had a history of being the responsible party for several technical issues causing 911 outages across many states in the United States.
In April 2014, Intrado was partially responsible for a 14-state 911 outage that affected an estimated 11 million people and 6,000 emergency help calls. As a result, the FCC fined Intrado $1.4 million.
In November 2019, Intrado agreed to pay $175,000 to the US Treasury due to glitches in their system that occurred in August 2018 that left millions without access to 911 access for 65 minutes across 6 states.
In September 2020, 911 outages were reported across 14 states for more than an hour due in part to Intrado. 
Between 2002 and 2013, West Corporation invested approximately $2.7 billion in strategic acquisitions.
