KNOXVILLE, Tennessee — UPDATE 10:30 AM MONDAY: Knox County 911 service has been fully restored after a weekend of problems related to Friday's downtown Nashville bombing.
"We appreciate our dedicated team that worked through the temporary interruption of service to provide emergency communications to our community," the center tweeted Monday morning.
The suicide bombing near an AT&T center caused a chain reaction of transmission and communications problems across parts of Tennessee.
UPDATE (Dec. 26): Officials said that Knox County's E911 call center was back up and running on Saturday after centers across the state experienced disruptions.
An explosion in Downtown Nashville impacted communication infrastructure across Tennessee, Kentucky and Northern Alabama, officials said.
Officials also said that the call center's systems had backup solutions in case services experience disruptions again.
"We have a redundant system that's currently working and we're grateful for that," said Brad Anders, the Executive Director of if Knox County 911. "It's fluid and we're hoping that AT&T can get everything back online, not just for our sake but for the sake of everybody across the state."
Anders also said that workers were looking back at the log calls they got during the disruption to make sure everyone is safe.
