Play it again, Sam: Verizon customers in locations across the United States are unable to connect to the LTE data network this morning. The outage may or may not be nationwide, but customers in Houston, Dallas, Memphis, various California locations and New York City are all reporting issues. Verizon customer service has confirmed connection problems, and assures applicants that it's working on them. 3G data and voice seem to be unaffected so far.
This has become a recurring problem for Verizon, which had no less than three major outages in December of 2011 - just a few weeks after the releases of major 4G phones like the HTC Rezound and Motorola DROID RAZR. It didn't help that Verizon's marketing has featured the "largest 4G LTE network in the country" and "the most reliable major network" (paraphrasing) for months. The outages varied in breadth and duration, but the longest was a complete shutdown of every LTE network that lasted more than a day.
Verizon previously indicated various technical issues behind the interruptions of service. They basically blamed new challenges in the LTE standard, but that's little comfort to customers who were sold on greater speeds on a big, reliable network - not to mention the fact that data caps now limit how much they can do and when. Verizon's reputation as the best large-scale cellular provider is taking some big hits, no doubt about it. We'll see if they can make amends, or if their competitors can capitalize on the misfortune.
Feel free to report any Verizon issues you're having in the comments section, and be sure to include your city and the time that the problems started or ended.
