The agency tweeted, “We are currently running at normal operations. The root cause has still not been identified.  Our staff and vendors will continue to search for the cause.”

The North Texas Council of Governments said this wasn’t part of some malicious attack.

“We had many contingencies in place so an outage like this could not occur,” said Christy Williams, with the NTCOG. “Unfortunately, it did. We are taking every step to make sure it never does again.”

NTCOG is working to update the system and Williams said there could be more service failures during that process.

Meantime Williams said she could not go into any greater detail about what went wrong Wednesday afternoon.

“The design of our network is a matter of national security so I can’t go into those details,” she said.

The affected areas included:

Collin County

Erath County

Ellis County

Hood County
