LTE outage embarrasses Verizon

network outage that affected its customers last week, Verizon Wireless revealed via Twitter that its 4G LTE network is back up and running, reports Cnet.

The carrier acknowledged that it had determined the cause of the service interruption, but did not provide further explanation as to what caused the outage.

When asked for more specifics, Verizon spokesperson Brenda Raney said in an e-mail: “Our 4G LTE network is up and running. Our network engineers and vendors quickly identified the issue and solved it.”

The outage prevented any new LTE device activations, most notably the HTC Thunderbolt, the only smartphone so far available on Verizon's super high-speed 4G network, states PC Mag.

An HTC spokesperson said he was not aware of any negative effect on sales during the outage, and a Verizon spokesperson declined to comment.

During an earnings call last week, Verizon said it had more than half a million subscribers for its LTE network.

The failure was a major embarrassment for Verizon, which markets itself as having a more reliable network than its main rival, AT&T, writes PC World.

It was also a reminder that even the most sophisticated systems can fail.
